I have a question for all you guys promoting the homozygous black continentals: How did those breeds become homozygous black? and won't this most certainly effect the amount of heterosis since the breed that made them black will be in the cross?
This is good question, sooknortex, and shows that you are thinking!
The breeds became Homozygous Black by using Homozygous Black Individual Bulls of whatever breed they utilized, probably ANGUS originally. And yes, you are correct - genetically, the heterosis will be affected by virtue of the fact that there will be a higher percentage of one breed present, however, that can be balanced out by future meticulous crosses in subsequent matings. One must determine what factors are important to their breeding program in ensuing generations, and plan their future mating combinations accordingly.
Their are always choices. Nothing is easy!
