Good stuff, thanks. I wasn’t thinking about the ontogenetic change in Black Rats, but you bring up an interesting point, in the whitesided Black Rat, the adults never are white side with solid black backs are they? It seems they retain more of the juvenile pattern along the back and never complete the color change. Now I’m wondering if a whitesided Black Milk would result in a whiteside with solid black back? AAAHHH So many alleles- so little time!
