curly hair is inherited in an autosomal dominant fashion. attached earlobes are autosomal recessive. a man and a woman who are both heterozygous for both traits marry. answer a and b using: h/h for hair and e/e for ear lobes. a. Assume these traits exist on separate chromosomes and exhibit independent assortment. what is the probability this couple will have a child with straight hair and unattached ear lobes? b. Assume thesetraits are linked on the same autosomal chromosome. the dad alleles are linked: H---e and h---E. The mom's alleles are linked: H---E and h---e. What is the probability this couple will have a child with straight hair and unattached ear lobes assuming no crossover event occurred?
