Multilocus and Multitrait Measures of Differentiation for Gene Markers and Phenotypic Traits

摘要: Multilocus measures of differentiation taking into account gametic disequilibrium are developed. Even if coupling and repulsion heterozygotes cannot be separated at the multilocus level, a method is given to calculate composite measure (CF(st)) zygotic which accounts for allelic associations combining both nongametic effects. Mean maximum differentiations may relevant when computed. Maximum highest eigenvalue F(st) matrix, whereas mean corresponds value all eigenvalues matrix. Gametic has stronger effect on than takes anisotropy that exist between within- between-population components disequilibria. calculated set 81 Quercus petraea (sessile oak) populations assessed with eight allozyme loci two phenotypic traits (bud burst height growth). The results indicate increases as more (traits) considered remains constant or decreases. Phenotypic exhibit higher population allozymes. applications uses further discussed.
