So I'm going to start getting into kenyans as they are really cool little boas. I haven't fully started researching yet but I have come across something that stumped me and I'm curious on an answer. I have found out nuclears are a line bred trait. But what exactly is a line bred trait? I know it has something to do with inbreeding (brother x sister) but what does it do? Does it mean a nuclear to a anery won't yield anery nuclears at some point?


Thanks.
Kevin.

Anyone? :/

I don't know about kenyans specifically, but generally, "line bred" means that a degree of inbreeding is done to make a trait more prominent.

For example, say you have a snake species; male & female. The male has a super "busy" pattern & the female has a super "reduced" pattern. If you wanted to make more snakes with a reduced pattern, you'd breed the male & female, hold back the most reduced & breed them back to mom. From those babies produced, you'd hold back the most reduced & breed them to eachother & / or mom.

Basically, it's not a recessive / co-dom / dom trait, it's just something you're selecting for in the offspring & keep breeding the most extreme examples in the hopes that you'll make more of what you like.

It doesn't have to be pattern either, you can breed for colour, size, etc. etc.

So in summary, it's just a selectively bred trait over several generations. I hope that makes sense & helps you a bit with the answer to your question. ~

Yes, that does make sense. I was just confused becasue it wasn't labeled as a dom/codom/recessive gene. People just said it was line bred and I wasn't 100% sure on what it was.

Thanks.

Kevin,........... The nuclear trait your talking about was developed by Roy Stockwell in Canada. Roy basically held back the best looking babies he produced from his breedings and continually refined the color of the offspring in succesive generations. What you see now is the result of that work.
