(Phys.org)—Although humans are a single species, not all genetic variation is shared between populations – and the ability to sequence our entire genome has allowed scientists to catalogue mutations that occur in one ...
Scientists at the University of Utah identified mutations in three key genes that determine feather color in domestic rock pigeons. The same genes control pigmentation of human skin.
