>>I'd like to see the results of the following matings:

1) a peanut butter male x a "het" female like in the picture.

2) A peanut butter male x a normal female

3) A normal male x a "het" female like the one in the picture, and then cross the male x female babies, male babies to normal females, and female babies to peanut butter males.



I'm still trying to clarify some things in my own mind. The peanut butter males are almost white at hatching and darken to a peanut butter shade over time. How long does this process take?



How old were the three snakes in the top picture in the original post?



The males like the one marked "male het PB" in the original post come out of the egg jet black and lighten a little. From context, he seems to be about 6-7 months old when the picture was taken. Is this age correct, and would he stay about that color for the rest of his life?



The female marked "female het PB" in the original post also seems to be about 6-7 months old. Is the coloring typical of the females het for pb? What color was she when she hatched, did she darken or lighten with age, and will she stay about the same color?



I'm going to use the letter A to refer to the single male marked "het male pb" in the original post. And I'm going to use the letter B to refer to the single female marked "het female pb" in the original post.



>I bred the PB male to a Beard line hypo and all the neonates came out normal (double?)hets.



How many males, and how many females? How many males looked like A? How many males looked like B? How many females looked like A, and how many females looked like B? Were the babies retained long enough so that you could tell the difference?



>I also bred a PB to a normal florida king and all the neonates came out normal.



How many males, and how many females? How many males looked like A? How many males looked like B? How many females looked like A, and how many females looked like B? Were the babies retained long enough so that you could tell the difference?



>All the breeding I have dome where from a PB male to a het female. I had a varieance of PB's within each clutch and definet het males and females.



Did the female adults all look like A, all look like B, or did some look like A and some like B?



Lump the babies from all the PB male x like A females together and answer the questions below. And lump the babies from all the PB male x like B females together and answer the questions below for them.



How many males, and how many females? How were the babies sexed and at what age? How many males were PB? How many males looked like A? How many males looked like B? How many females looked like A, and how many females looked like B? Were the babies retained long enough so that you could tell the difference?



>The originator and his friend bred the two hets together to produce the first PB's males. Females were ratained for back breeding to the PB males.



Am I correct in assuming that of the original two snakes, the male looked like the snake I'm calling A? Did the female look like either A or B or like neither one?



Of the male babies from this mating, how many were PB males, how many males looked like A, did any males look like B, and did any males look neither PB nor like A nor like B? Of the females from this mating, how many looked like A, how many females looked like B, and did any females look like neither A nor B?



I wish I had more answers than questions. Basically right now I'm trying to list all the different phenotypes and assign numbers of babies to them for various matings.
