After losing 50 pigs to pseudorabies, Liam is distressed when he notices the new pigs he purchased showing the same symptoms. His vet comes out to look, asking Liam questions to try to pin down this recurring infection. Which question is MOST likely going to point the vet to the reason for the reinfection?

The answer would be dogs.

The answer would be c, white eyes are homozygous recessive. in the early 1900s, morgan conducted several experiments with vinegar  flies (drosophila). one  sample revealed an anomaly: a  white-eyed, single male fly. he attempted to breed this fly with the typical red-eyed females. the offspring were all red-eyed. using flies from this new generation (brother-sister pairs)  produced some red-eyed and a few white-eyed flies. the white-eyed were all male. in later experiments, he was able to produce white-eyed females. this proved that white eyes are not lethal to either sex (ruling out a and b). since the percentage of white eyes to red eyes is so low, white eyes are not a dominant trait. it would be a recessive trait. 

C. the area was covered by water. let me know if this
