im thinking about getting into breeding...but i've got some questions about breeding...

if i breed a 100% het albino to a 100% het albino, what do i get?

is it half albinos, half hets?
(i'm unclear as to how this works)

what if i breed an anery het albino to an albino?
do i get just albinos & hets, no aneries?

im interested in breeding some boas that will produce a variety of morphs...what is my best option?

im not sure how to use the sites that lay out the results of genetics...if someone could guide me how to use those i would appreciate that too!

thanks so much!

Albino is a recessive trait where an offspring has to get one copy of the recessive gene from each parent in order for the trait to show. Since each parent is a het, they will each pass on an albino gene to 1/2 of their offspring. Tpo get a fianl result you have to multpily the probabilities or 1/2 x 1/2 = 1/4 of the babies would be albino. Of course real woirld actuals can and do vary. The remainder of the litter would be 1/4 het albino from dad, 1/4 het albino from mom and 1/4 normal from both but since you can't visully tell them apart, they're called 66% hets or two out of three chance any individula is a het.

Anery is also a recessive trait so look at each trait seperately....

anery x normal = all 100% hets

Albino x het albino = 1/2 albino, 1/2 het albino.

combined back together =

1/2 albino, het anery (or albino het snow)
1/2 het albino, het anery (or DH snow)

IMO a great choi=ce is one where the expected offspring fall inot several visually distinguishable phenotypes like

Anery het albino x albino et anery =
1/4 snow
1/4 albino het anery
1/4 anery het albino
1/4 DH snows

To maximize the number of phenotypes from a given pairing, look at each morph trait seperately and have them follow these rules:

Recessive trait - one parent homozygous (or showing the trait) and the other het (does not matter which is which)

Dominant trait - one parent being het, other normal

Codominant trait - both parent being het
