Genetics to knowledge: Aa dd rbrb (possibly carrying Mink, Chocolate and Dumbo)

Yeller' is a very sweet lad, he wasn't supposed to stay, but we decided to keep an extra rat from his litter, and he seemed the best candidate. He's very sweet natured, although his colour is more than a bit odd! He's is so named because he's very yellow, and we want to see how this colour develops as he ages.
