Directions: Solve these genetic problems. Be sure to complete the Punnett square to show how you derived your solution. 1. In humans, the brown-eye (B) allele is dominant to the blue-eye allele (b). If one heterozygote and one homozygote mate, what will be the likely genotype and phenotype ratios of the offspring. GR: PR: 2. In pea plants, purple flower color (P) is dominant over white flower color (p). Show the cross of a purple flower color that is heterozygous for pea flower color with a white flower color. Summarize the genotypes and phenotypes of the possible offspring in ratios. GR: PR: 3. In guinea pigs, the allele for short hair (H) is dominant to long hair (h). Two short-haired guinea pigs are mated several times. What are the most probable genotypes of each of the parents? What will be the likely genotype and phenotype rations of the offspring? Explain using a Punnett square. Parental Genotypes: GR: PR:
