The recombination pattern may include interference. Evolutionists have debated whether population-genetic parameters, such as effective population size and migration rate, differ between males and females. (2) Despite constancy of environment, punctuated evolution may obtain; populations may experience rare adaptations asynchronously, permitting incompatibility. We show that the evolution of trait means within niches depends on the overall evolution in the whole system, and in general, optimum phenotypic values are not attained. Since there is some uncertainty about the details of the microsatellite mutation process, we consider several plausible mutation schemes and estimate the variance in mutation size simultaneously with the demographic parameters of interest. THE EVOLUTION OF INTERFERENCE - REDUCTION OF RECOMBINATION AMONG 3 LOCI. View details for Web of Science ID 000167167000002. Evolutionary equilibria and trajectories of gene-culture interactions involving sex-chromosomal distorter alleles may produce severely male- or female-biased primary sex ratios and adult sex ratios in populations. Statistical properties of the symmetric stepwise-mutation model for microsatellite evolution are studied under the assumption that the number of repeats is strictly bounded above and below. We also identified different patterns of variation across categories of gene function. A large fraction of the 81 screened markers was found to be associated with quantitative traits. View details for Web of Science ID 000185007500005, View details for PubMedCentralID PMC2697980. The evolution of fitness interactions between genes at two major loci is studied where the alleles at a third locus modify the epistatic interaction between the two major loci. Overall, we believe that our results provide evidence for selection on several complex traits that has caused changes in allele frequencies and/or elevated iHS scores at a number of associated loci. Pop. We found that high levels of social learning are associated with a larger amount of more persistent knowledge, but a smaller amount of less persistent expressed behaviour, as well as more uneven distributions of behaviour, as individuals concentrated on exploiting a smaller subset of behaviour patterns.

The increase in number of alleles seems to reduce the possible extent of association between the loci. We apply our results to microsatellite data from the Human Genome Diversity Panel, and we examine the male and female migration rates implied by observed F(ST) values. All on FoxSports.com.

B., Godbout, R., Katyal, S., Smith, C., Hudson, Q., Sinclair, A., Mizuno, S. On the meaning of non-epistatic selection. We also find sparser networks to be more stable, which may help to explain why they seem to be favored by evolution. Weissman, D. B., Feldman, M. W., Fisher, D. S. Cumulative cultural dynamics and the coevolution of cultural innovation and transmission: an ESS model for panmictic and structured populations. We extend Orr's model to the finite loci case, which can limit incompatibility. Sharp differences exist between the two generations in the reasons that underlie their intentions. We explore whether mortality is related to adoption in a historical Taiwanese population where adoption rarely occurred among kin. It is speculated that this occurs because the mean fitness in such models is locally increasing as a function of the degree of epistasis. We also show that the mechanism responsible for this effect has been out of the purview of previous theory, because it operates during the evolutionary transient, and that the breaking down of favorable genetic combinations is an integral part of it. Adopted children often experience health and well-being disadvantages compared to biological children remaining in their natal households. We also found that the number of loci, as well as recombination rates substantially affect ERD. This result supports the position of the Samaritans that they are descendants from the tribes of Israel dating to before the Assyrian exile in 722-720 BCE. Rhines, A. S., Feldman, M. W., Bendavid, E.

This assumption is unlikely to hold for polymorphic sites within the same locus. Transmission matrices of the teacher/leader type, and of parental type have been specifically considered, as well as social hierarchies. School: Stanford University (Palo Alto, CA) Debut: July 13, 2018 (Age 31-025d, 21,723rd in major league history) In contrast to what was observed for AFLP-based diversity, the frequency of heterozygotes based on microsatellites was comparable among all populations. Non-epistasis may also be quantitatively defined in terms of measures of interaction used widely in statistics. Was inter-population connectivity of Neanderthals and modern humans the driver of the Upper Paleolithic transition rather than its product?

WASHINGTON (CN) — Unequivocal in their testimony, three constitutional law scholars summoned before the House Judiciary Committee told lawmakers Wednesday that President Donald Trump committed offenses that should lead to his impeachment. We characterize the time dependency of the human mitochondrial hypervariable region one mutation rate by generating 14 new phylogeny-based mutation rate estimates using within-human comparisons and archaeological dates. Christiansen, F. B., Otto, S. P., Bergman, A., Feldman, M. W. Microsatellite behavior with range constraints: Parameter estimation and improved distances for use in phylogenetic reconstruction. Jayakar suggested a model for the two-locus control of sex determination in the mosquito Aedes aegypti (1981, Theor. We find that individuals from the Kalahari carry a higher oral pathogenic microbial load than samples surveyed in the Human Microbiome Project. We show that when linkage in the three-locus system is tight, an increase in the frequency of a modifier allele that induces either more negative or more positive epistasis is possible. Culture amplifies the capacity of human beings to modify sources of natural selection in their environments to the point where that capacity raises some new questions about the processes of human adaptation. We propose a stepwise mutation model to describe the dynamics of DNA fingerprint variation in Mycobacterium tuberculosis. Phylogenetic trees were constructed from these data. Zhivotovsky, L. A., Feldman, M. W., Christiansen, F. B. In this study, liquid chromatography/electrospray ionization/quadrupole ion trap mass spectrometry was used to allelotype 13 Y-chromosomal and 15 autosomal microsatellites in a sample of 12 Samaritans chosen to have as low a level of relationship as possible, and 461 Jews and non-Jews. The properties of this new semi-symmetric model are compared with those of the classical symmetric model. Evolution of resilience in protein interactomes across the tree of life. Creanza, N., Ruhlen, M., Pemberton, T. J., Rosenberg, N. A., Feldman, M. W., Ramachandran, S. The role of climate and out-of-Africa migration in the frequencies of risk alleles for 21 human diseases. Feldman, M. W., CAVALLISFORZA, L. L., Peck, J. R. SELECTION IN COMPLEX GENETIC SYSTEMS .6. The theory of evolution at a selectively neutral locus that controls the recombination between two major loci that are under selection is studied. This remembrance focuses on his work in multi-locus population genetics, primarily on the interaction between genotypic selection and the rate of recombination. Our previous research on evolution of modifiers of epistasis in diploid systems has indicated that the strength of positive or negative epistasis should increase provided linkage disequilibrium is maintained.

Diversity at the individual and population levels, as well as at the level of cultural homogeneity within groups, depends critically on the details of population demography and the individual and social learning rules. In our discussion of communication, cost factors for the act of communication have been omitted. If recombination is already fairly frequent, there may be selection for increased recombination. The transmission matrix W has as its elements the proportional contributions of each individual (i) of one generation to each individual (j) of another. The seed sets also permit a successful reconstruction of a phylogenetic tree of life. We present three evolutionary genetic models that incorporate both this selection pressure and the effect of deleterious mutations to elucidate the conditions under which imprinting could evolve. Louis Michael Seidman (born 1947) is the Carmack Waterhouse Professor of Constitutional Law at Georgetown University Law Center in Washington, D.C., a widely read [citation needed] constitutional law scholar and major proponent of the critical legal studies movement. We find that African hunter-gatherer populations today remain highly differentiated, encompassing major components of variation that are not found in other African populations. Following a chicken interline cross (White Plymouth Rock background), we produced a multigenerational resource population based on 4 pedigreed generations. Genome-wide association studies (GWASs) seek to understand the relationship between complex phenotype(s) (e.g., height) and up to millions of single-nucleotide polymorphisms (SNPs). Second, the waiting time is calculated as the expected value of a heterogeneous geometric distribution obtained from a branching process approximation. Genetic data and the African origin of humans, Statistical properties of the variation at linked microsatellite loci: Implications for the history of human Y chromosomes. Michael Feldman (born January 21, 1926 in Tel Aviv, † 2005) was an Israeli molecular biologist, developmental biologist and immunologist and professor at the Weizmann Institute.. Feldman studied biology at the Hebrew University in Jerusalem, where he received his doctorate. Here, we study the dynamics of population statistics and the genetic distance between two populations under multiple stepwise mutations with linear bias and random drift.

Cultural evolutionary theory: How culture evolves and why it matters. Polymorphisms at di-, tri-, and tetranucleotide microsatellite loci have been analyzed in 14 worldwide populations. Here we characterize the genomic variation represented by 16,297 X-linked SNPs genotyped in the CEPH human genome diversity project samples.We found that X chromosomes tend to be more differentiated between human populations than autosomes, with several notable exceptions. Does China's Anti-Poverty Relocation and Settlement Program Benefit Ecosystem Services: Evidence from a Household Perspective. Corresponding trees were topologically similar for the two data sets, with the exception that the (deltamu)2 genetic distance reliably distinguished groups from different continents for the larger data set, but not for the smaller one.
