Rates And Patterns Of Evolution In A Duplicated Genome In The Family Catostomidae, Megann Michelle Schmidt
Honors Program Theses
Whole genome duplication (WGD) is a process in which the entire genome of an organism is duplicated, making redundant genes which are subject to unique evolutionary forces. Various modes of selection create different genetic fates such as retention of ancestral function, development of new function, or loss of function. Because of these differing fates, WGD is hypothesized to be a major driving force behind diversification. In this project, DNA sequences from fish species in the family Catostomidae were examined to observe patterns of evolution following a known WGD. Gene trees were generated for 179 loci to determine the amount of …
