Figure 1From: Evolutionary patterns of two major reproduction candidate genes (Zp2 and Zp3) reveal no contribution to reproductive isolation between bovine speciesThe Bayesian trees of the Zp2 ( a ) and the Zp3 ( b ) haplotype sequences from seven species of the Bovini tribe. The haplotype sequences include both coding and non-coding parts. The domestic sheep and goat are used as the outgroup species. Numbers above nodes indicate posterior probability values.Back to article page
