摘要: Expressions describing the accumulation of gene correlations within and among lineages individuals a population are derived. The model permits different migration rates by males females accounts for various breeding tactics lineages. resultant equations enable calculation probabilistic quantities fixation indices, loss genetic variation, inbreeding, coefficients relationship at any generation. All indices were found to attain asymptotic values rapidly despite consistent variation inbreeding population. time required values, however, was prolonged when flow relatively low (less than 20%). degree differentiation groups, coefficients, be primarily functions groups rather groups. Thus, value S. Wright9s island is not appropriate differences populations. An alternative solution provided that under limited conditions will reduce original model. evolution polygynous appears more favorable promoting intragroup modification rates. Inbreeding variance effective sizes derived populations structured tactics. Processes size result in concomitant increase size.
