9. In guinea pigs, rough coat is a dominant gene and a smooth coat is the recessive allele. A rough-coated male is mated with two rough-coated females. Female A has produced 14 young after 3 matings, all rough coated. Female B has produced nine young after 3 matins. Seven of the offspring are rough coated and two are smooth coated. What are the genotypes of the three parent animals? Use the Punnett square to support your result.

8. Achondroplasia is a dominant form of dwarfism in humans. Heterozygous individuals exhibit the dwarfism trait, while homozygous dominant embryos die before birth. Suppose that an individual with Achondroplasia is expecting a child with an individual of normal height. What are the chances that their child will exhibit the dwarfism trait? Must show both genotypic and phenotypic analyses. 9. In guinea pigs, rough coat is a dominant gene and a smooth coat is the recessive allele.

Maple syrup urine disease is a rare inborn error of metabolism. If untreated, affected children die soon after birth. The disease tends to recur in the same family, but the parents of the affected individuals are always normal. What does this information suggest about the transmission of the disease?
