- 1. If one parent is homozygous dominant for a trait, that parent's genotype might be GG. If the other parent is homozygous recessive for the same trait, that parent's genotype would be gg. What are the possible genotypes of their offspring? b. How many different phenotypes might we possibly see in their offspring? 2. If a male is homozygous dominant for a trait, that parent's genotype might be DD. If the female is heterozygous for the same trait, her genotype would be Dd. a. How many genetically different sperm can the male produce? b. Using a Punnett square, determine the expected genotypic ratios of their offspring. What are the expected phenotypic ratios? 3. In garden peas, the gene for red flowers (R) is dominant over the gene for white flowers (r).
