breeder

Breeders have figured out that if they can take one haploid set of chromosomes from a cross and copy it (or double it creating a double haploid), they will have a pure line almost instantly.

The number of souls in this kingdom being usually reckoned one million and a half, of these I calculate there may be about two hundred thousand couple whose wives are breeders; from which number I subtract thirty thousand couples who are able to maintain their own children, although I apprehend there cannot be so many, under the present distresses of the kingdom; but this being granted, there will remain an hundred and seventy thousand breeders.

Since the breeders started coming here, you can never tell who likes cock.
