Analysis of population structure in autotetraploid species.

摘要: Population structure parameters commonly used for diploid species are reexamined the particular case of tetrasomic inheritance (autotetraploid species). Recurrence equations that describe evolution identity probabilities neutral genes in an "island model" population derived assuming inheritance. The expected equilibrium value FST is computed. In contrast to diploids, correlation between individuals within populations with respect (FST) may vary among loci due segregation patterns under and consequently inappropriate estimating demographic such populations. We thus define a new parameter (rho) derive its relationship Nm. This shown be independent from both selfing rate proportion double reduction. Finally, statistical procedure required evaluate these using data on gene frequencies distribution autotetraploid developed.
