Your guess is correct because of the visual pied parent. All of the offspring from your pied will get one copy of the pied gene from the female pied. Since your other spider is a het he only has one copy of the gene and will pass it on to 50% of his offspring. That's why you get (on average) half the offspring being visual pied. The other two are just hets (but they are 100% hets) because they are guaranteed a copy from the mother but missed out on a copy from the father.Originally Posted by BCS
