I'm going to use white collar as an example here, but a variety of desirable traits could be used interchangeably. For the sake of discussion though, let's say you're trying to selectively breed for white collars. When choosing your breeders, would you go for one with a big white collar that was produced by parents with little or no white collar or would you prefer one with a small dirty collar from parents with big white collars that consistently produce white collared offspring? The reason I ask is because I've seen breeders sharing pictures of siblings and other closely related animals, oftentimes with more desirable coloration or other features than the animal for sale. So I'm wondering if a less nice individual from a stellar lineage is more desirable than a standout individual with less desirable lineage? My instinct would be to go for the latter and prioritize the animal being bred over its parents/grandparents when selecting for a particular trait, but I'm curious if those of you who've produced a lot from different pairings think differently?
