However, if you factor in either of the two PP or UU genomes, then you are creating EP, PE, UE, and EU pairings. If we were to, as you say, assume the Earth genome is the recessive trait, then those pairings would become Pe, and Ue, since recessive traits can't lead the pair naming. Unless of course the unicorn and pegasi breeds were a result of inbreeding and mutation amongst Earth pony pairs. |
