tailieunhanh - Pinning down ploidy in paleopolyploid plants

Fractionation is the genome-wide process of losing one gene per duplicate pair following whole genome multiplication (doubling, tripling, .). This is important in the evolution of plants over tens of millions of years, because of their repeated cycles of genome multiplication and fractionation. One type of evidence in the study of these processes is the frequency distribution of similarities between the two genes, over all the duplicate pairs in the genome. |
