Using allele frequencies and geographic subdivision to reconstruct gene trees within a species: molecular variance parsimony.
We formalize the use of allele frequency and geographic information for the construction of gene trees at the intraspecific level and extend the concept of evolutionary parsimony to molecular variance parsimony. The central principle is to consider a particular gene tree as a variable to be optimized in the estimation of a given population statistic. We propose three population statistics that ...
متن کاملAnalyses of gene frequencies.
Models of variance components and their intraclass correlational equivalences are developed for genes falling into various categories of subdivisions within a population. Estimable functions are elaborated demonstrating that intraclass correlations can be estimated only relative to that for the least related genes in the informational system. The effects of different types of subdivisions-and o...
متن کاملAnalyses of gene frequencies of mates.
A genic analysis of variance of data on mate pairs for a codominant gene is developed. This analysis provides estimators of the correlation, F, of genes within individuals, of the correlation, Theta, of genes between mates, and of various variances-all relative to the correlation or variation among genes of nonmates. The data are manipulated into marginal distributions to produce another method...
متن کاملThe Distribution of Gene Frequencies in Populations.
The effects of the various evolutionary factors-mutation, cross breeding,. selection and inbreeding-can be reduced to common terms by considering the rates of change which they tend to bring about in the relative frequencies of alleles.' In the absence of such factors, there is constancy of gene frequencies from the symmetry of the Mendelian mechanism. The frequency (q) of a given gene changes ...
