In fruit flies, short wing is dominant to long wing. What are the genotypes and phenotypes of offsprings between two heterozygous short winged flies?
3. Mr. and Mrs. Banda both have tightly curled hair. (The hair form gene shows incomplete dominance. There
are two alleles, curly and straight. The heterozygote has wavy hair.) The Bandas have a child with wavy hair. Mr.
Banda accuses Mrs. Banda of being unfaithful to him. Is he necessarily justified? Why or why not? Use a genetic
diagram to support your argument.
4. A man with dark (dominant), curly (see problem I.5.) hair marries a woman with light, straight hair. Their
daughter, who happens to have dark hair, marries a man with light, wavy hair. Answer the following questions
about this dark-haired daughter and her family.
a. Draw a Punnett’s square for this marriage, and predict the phenotypic ratio among the offspring of the
daughter and her husband.
b. What is the chance that they will have a child with hair just like his or her father’s?
