The same candidate genes and the same autosomes are repeatedly used as sex chromosomes in vertebrates. Are these systems identical by descent, or are some genes or chromosomes intrinsically better at triggering the first steps of sex determination?
在脊椎动物中,相同的候选基因和相同的常染色体被反复用作性染色体。这些系统是通过同源性重复使用的,还是某些基因或染色体在引发性别决定的第一步时具有内在优势?
