2. In humans, acondroplasia “dwarfism” (D) is dominant over normal (d). A homozygous dominant (DD) person dies before the age of one. A heterozygous (Dd) person is dwarfed. A homozygous recessive individual is normal. A heterozygous dwarf man marries a dwarf heterozygous woman…….. a. What is the probability of having a normal child? _________ b. What is the probability that the next child will also be normal? __________ c. What is the probability of having a child that is a dwarf? __________
In humans, free earlobes (F) is dominant over attached earlobes (f). If one parent is homozygous dominant for free earlobes, while the other has attached earlobes can they produce any children with attached earlobes?
4. In humans widow’s peak (W) is dominant over straight hairline (w). A heterozygous man for this trait marries a woman who is also heterozygous. a. List possible genotypes of their offspring. b. List the phenotypic ratio for their children.
