Attached earlobes are recessive to free earlobes. what is the probability of having a child with attached earlobes when an individual with attached earlobes mates with an individual heterozygous for free earlobes? attached earlobes are recessive to free earlobes. what is the probability of having a child with attached earlobes when an individual with attached earlobes mates with an individual heterozygous for free earlobes? 25% 0% 50% 75%

I believe that the probability of having an individual with attached earlobes will be 50%. Since the attached earlobes is recessive then its genotype will be (ee), for the unattached ear lobes the genotype will be EE, Ee. Therefore, mating between an individual with attached ear lobes (ee) and one with unattached ear lobes, heterozygous, Ee,  the offspring will be; Ee, Ee, ee, or ee. Therefore; half of the offspring will have unattached ear lones (heterozygous) while another half will have attached ear lobes.
