what morph do the breed to get a brindle blackrat ,i am curious because i have a pair of them and i was wondering what morph type of black rat they used to get the brindle...thanks in advance.

A "Brindle" animal was bred to a naromal to produce "Het. for Brindles". The offspring were bred back together (or to the Brindle parent) to produce more Brindles.

but how did they get the first brindle to breed with was it an accedent ,did it just hatch out and someone called it a brindle?

I have a book that has a section about that animal. I will have to look into that. It is very rare for a mutation to just pop out of breeding two normals together. Most of the time, an "odd" animal is found in the wild & then bred out to be proven genetic. I'll look into that this evening....

I don't know what "brindle morph" you guys are talking about, I'm more into boas than colubrids, but the native black rats here are all brindle colored. Some are dark enough to be close to black, but the vast majority are a light to medium brown with crazy patterns. I've seen one that had enough red in it to make it seem light pink. Could you post a pic of this morph so I can see how it compares to what is normal here? Thanx

Hmmm...interesting indeed. In what part of the country do you see the light brown obsoleta obsoleta? I live in Tennessee and have known them to be jet black dorsally and white with black checkering anteriorly. I have seen a patterned juvie, but here in the mountains everyone knows them simply as the "blacksnake". I've seen a brindle morpf in a local petshop that had a light pink hue mixed with the brown...it was stunning!

Madison County, KY. About 2 hours from Knoxville. We call them blacksnakes here too, but they aren't really black. I've seen some pretty dark, but most are med brown and that one I described was awsome.

I live in Knoxville, and actually grew up in Hawkins County, which is about an hour and a half drive northeast. It is interesting how these two color variations are so close but look so differently. I'm thinking that the obsoleta around here are black 'cause of the mountains, where elevations tend to be colder (black better absorbs heat from the sun).
