Abstract:The evolution of chromosome numbers is an important but not fully understood aspect of eukaryotic evolution. Although we understand the types of karyotypic changes that can lead to chromosome gain and loss, we still do not understand why chromosome numbers in many plants and animals have an average ofn= 9. A recent hypothesis proposed that chromosome number reduction following whole genome duplication (WGD) in angiosperms is driven by an interaction between chromosome number and the strength of reproductive is… Show more
