According to recent research from the United States, "Divergence in mating signals is a primary factor leading to reproductive isolation, and thus, speciation. However, the genetic changes underlying such divergence are poorly understood, especially in vertebrates."
"We used two species of poeciliid fishes, Poecilia velifera and P. mexicana, to explore the link between genes and mating behaviors that has resulted in pre-mating reproductive isolation between these species. Using backcross hybrids created from the F1 male offspring of reciprocal interspecific crosses between a sailfin molly (P. velifera) and a shortfin molly (P. mexicana), we examined the effects ...
