| y chromosome phylogeny for cutthroat trout (oncorhynchus clarkii) subspecies is generally concordant with those of other markers. | sequence divergence was evaluated in the non-recombining, male-specific omyy1 region of the y chromosome among the subspecies of cutthroat trout (oncorhynchus clarkii) in the western united states. this evaluation identified subspecies-discriminating omyy1-haplotypes within a ∼1200bp region of the omyy1 locus and localized the region to the end of the y chromosome by fish analysis. omyy1 sequences were aligned and used to reconstruct a phylogeny of the cutthroat trout subspecies and related spec ... | 2013 | 23059727 |
