Cryptic Speciation and Characteristics of the Transition Bias Following an Example of the cytb Gene in Palearctic Mammals
A study of taxonomic differentiation and transition bias of the cytb gene, focusing on the early stages of speciation, was carried out in 15 subfamilies/families of five orders of Palearctic mammals. It was confirmed that the genetic differentiation among taxa of small and large mammals is shifted b...
