Good point! Also keep in mind when dealing with heterozygous co-doms you play the odds games. So you could do lesser x pastel and get no pastel lessers or get all pastel lessers. Just something to keep in mind.
Isn't a problem if you're breeding supers or homozygous recessives, because then you know with 100% certainty what is in the eggs, at least what that parent gave genetics wise.
