In humans a cloven chin (cleft) is due to a dominant gene, while an uncloven chin is due to its recessive allele. Long eyelashes are expressed as a result of a dominant gene, and short eyelashes are due to its recessive allele. Suppose a man with a cloven chin and short eyelashes marries a woman without a cloven chin and with short eyelashes. One of their children has a cloven chin and short eyelashes, while the second child has no chin cleft and short eyelashes.
a) What are the genotypes of the parents and the children?
b) What is the probability that a third child will have a chin cleft and short eyelashes? c) What is the probability that a third child will have no chin cleft and long eyelashes
