Diverse evolutionary rates and gene duplication patterns among families of functional olfactory receptor genes in humans
Fig 5
Families of human functional OR genes significantly differ in the number of syntenic genes in the outgroup species.
Comparison of numbers of syntenic genes in outgroups species among families of human functional OR genes. The comparison was statistically significant (P = 1.42×10−30) based on Kruskal–Wallis test.
