WebNov 26, 2015 · 1. The domesticated turkey originated in Mexico in about 800 BC. Their races, like races in humans, are defined by a superficial characteristic – plumage color – rather than full gene-based ancestry. Only a half dozen or so of the turkey’s 16,000 genes contribute to plumage color, just like a handful of our 20,000 genes impart skin color. WebIn fact, Hox genes are found in many different animal species, including mice and humans. Yes, you have your very own Hox genes! The presence of similar Hox genes in different species reflects their common ancestry: a Hox gene cluster was likely already present in a common ancestor of mice, flies, humans, and other animal groups.

WebMutations happen for several reasons. 1. DNA fails to copy accurately Most of the mutations that we think matter to evolution are “naturally-occurring.” For example, when a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation. 2. WebLeucism, also genetic, is the condition of partial or total loss of pigmentation.
