recessive gene n.
A gene that is phenotypically expressed in the homozygous state but has its expression masked in the presence of a dominant gene.
Recessive genes are in everything, is everything abnormal?
How can you develop two breeds from a single herd that consisted of both red and black animals and consider the herd that carries a recessive gene to be abnormal. Having a black angus herd today and them having a red calf would be abnormal, having a red angus herd today and them having a black calf would be abnormal. Red angus are bred to have red calves, is this abnormal. How many black angus herds are there that are having red calves, if you had one, you won the lottery. So if you mate a black animal to a white animal (example in my previous post) both are dominant but one of them will most likely be recessive in that particular mating. Would that be considered abnormal?
