A quick check in, an interesting coloration, and weather considerations.

Sunshine's babies are moving around a bit, though mostly they as you can see below huddle in the hay and fur and stay warm which is sort of their job in life right now. That said, the kit Above is sort of a mystery. As you can see it's already developed the silverish ticking that we see on the crosses between Umbra and any Creme, but it's FAR early, and much more pronounced than the norm.

Genetics Part 1: A Primer and a Quiz

Rabbit Genetics, Part 1:

Genes control everything in an animal, from temperament  to maximum size and growth potential.  It is why peanuts are born to dwarf rabbits and not in normal lines, and why some rabbits are lops or wooly. The easiest type of genes to see and study are the color genes, because it produces an obvious result that is only rarely affected by outside factors.  For this reason, I’m focusing on color so that you can get the idea.  

I’m going to assume you have the basics of genetics down, and can understand words like dominant and recessive.  I’m happy to answer questions in the comments!
