Sickle cell diseаse is cаused by а change in the gene fоr hemоglоbin, which is the oxygen-carrying protein in red blood cells. Individuals who are homozygous for thesickle cell trait often cannot endure exercise. The normal allele (N) is dominant over the allele responsible for sickle cell disease (n). Jerry Smith shows a normal phenotype. He married a woman with sickle cell disease. He was worried about the probability of them having kids with sickle cell disease. Genetic tests were run, and geneticists informed them that all their kids will be carriers but they won't show the disease. What are the genotypes of Jerry and his wife? Explain your answer using punnet square. (4 pts) Jerry's son married a woman that is heterozygote for this trait. What are their respective genotypes? (2 pts) What would be the possible genotypes and phenotypes ratios of their children? Use a punnet square to show your answer. (4 pts) Is the cross in (c) an example of monohybrid or dihybrid cross?
