differenece between 66% and 50%

Ok...i know there is 50% hets and 66% hets. Both of those mean possible hets, right? So whats the difference?

When breeding recessive trait animals:

A 66% possible het is the normal looking offspring from a het to het breeding

A 50% possible het is the normal looking offspring from a het to normal breeding

All animals from a homozygous to heterozygous breeding will be 100% het

Hope this makes sense!

o0o0o..i see....Thanks! Thats been on my mind a while and i just wanted to figure it out

A 50% het means that it has a 50/50 chance that it carries one copy of the gene, and a 66% means that it's got a 66% chance that it carries one copy of the gene. Also, if a gecko came from a homozygous to normal breeding, all the offspring would be 100% het. But, this math only applies to simple recessives (the 3 albinos, blizzard and patternless)

I wanted to correct myself since I typed so fast.

All offspring from homozygous to normal will be 100% het

Yes, this is with recessive traits.

Yes, this is with recessive traits.

This is true for all mutant genes. It doesn't matter whether the mutant is dominant, codominant, or recessive to the normal gene. The only difference is that with a recessive mutant, the het animal looks normal. With a dominant or codominant mutant, the het animal does not look normal.
