To expand on my cryptic remark. The macaque and green monkey proteins are 100% identical to human over the aligned sequence. The two chimp proteins and the gorilla protein are rps4y, the y-linked protein. Do you have some other protein in mind?

No, the proteins were on the Y that were farther than the chicken. It was not evident on the match as they were not identified as such on the comparison lines. The opposum both X and Y are farther away than the chicken and they have less identities than the chicken.
