Question

The gene l determines hair length in rabbits. the gene b determines hair color. a rabbit with long, black hair is crossed to a rabbit with short, white hair. all the offspring have long, black hair. what are the genotypes of the parents?

Answer 1

The parents most likely have short white or short black hair as recessive traits, while long black hair are dominate traits. It could be that the short white hair of the one rabbit was a mutation, therefore is less likely to be passed to it's offspring.
