What are your opinions on hets?

[Eric Alan]

well I know that they would be het or not het; but wouldn't breeding two 100% percentages together make the babies that are het 100% or only 66%? This is where I really have trouble is figuring out the percentages.

A picture is worth 1000 words:


In this example, lets say blue is Piebald - a recessive trait. Both parents are 100% het Piebald (not visual, but carrying the trait). Of the offspring, there is a 1/4 chance at a Piebald (visual recessive). Of the other three, only 2/3 are carrying the Piebald trait - the other 1/3 is not. Because you can't tell which of the non-visual offspring are carrying the Piebald trait, all of the non-visual offspring are considered 66% hets.

Better?
