List and describe the molecular (sexual) mechanisms that lead to genetic variation in gametes
(offspring):How does incomplete dominance differ from codominance?Most albino children are born to normally pigmented parents. Albinos are homozygous for the recessive gene (aa). What can you conclude about the genotypes of the nonalbino parents?Why do males always express an X-linked recessive allele?What is polygenic inheritance?A woman with type A blood has two children. One has type O blood and the other has type B blood. What is the genotype of the mother? What are the genotype and phenotype of the father? What is the genotype of each child?What are epigenetic marks, and what is their significance?What is genomic imprinting, and what is its significance?A couple has sought genetic counseling – the wife is concerned because she is unexpectedly pregnant and her husband’s brother died of Tay-Sachs disease. She can recall no incidence of Tay-Sachs disease in her own family. Do you think biochemical testing should be recommended to detect the deleterious gene in the wife? Explain your response:
