Polymeric genes can control alternative traits. In this case, they are inherited as a non-cumulative polymer. In chickens, the feathering of the legs is determined by two pairs of polymeric noncumulative genes. If at least one of them is in a dominant state, chickens will have feathered legs. If all genes are recessive, then the legs will be unfeathered. What is the likelihood of chickens with unfeathered legs from crossing a diheterozygous rooster and a chicken heterozygous for one of the genes?
The probability of chickens with unfeathered legs from crossing a diheterozygous rooster and a chicken heterozygous for one of the genes is 0%.
