Does anyone know of the outcomes of a 1st time heifer and 1st time bull, brother and sister,that don't look nothing alike breading each other? Their mothers are two different breeds, but their dad is the same bull.Is it likely the calf will be deformed are will be a runt?

The old stories about two headed calves or six eyes etc is bull. Unless the bull has hidden negative or undesireable traits the calf may or may not be as growthy. That's caused by the increasing of matched gene pairs (homozygosity), but it could also match up desireable traits. With in/linebreeding you have to be willing and able to cull mercilessly. Any negatives must be eliminated in breeding animals.
