Hi, Back in the day when you could only get wild caught I acquired some Greenish rat snakes.
(Black/yellow intergrade species).
I managed to breed a pair and produced some offspring.
I bread them back to each other and produced a pair of Hypos. (see the pictures below.)
The hypos combined breed true and it worked like a recessive gene when bread out. So this was not just a colour difference.
However, due to life taking a bite out of me I had to give up keeping snakes for a while. I lost the line and could not find it again.
Question: has anyone seen any of these? are any still around, or did the line die out.
