Triple X syndrome is a rare trisomy, affecting 1 in 1000 females. A mother who is a carrier for male pattern baldness, an X-linked recessive disorder, has a daughter with triple X syndrome with a man who has male pattern baldness. The daughter does not have male pattem baldness. - List all possible genotypes for the woman with triple X syndrome. Note which chromosomes came from the mother and which came from the father. - For each possible genotype, diagram how the nondisjunction oceurred. Note whether the nondisjunction occurred in meiosis I or melosis II. - Which genotypes are not probable? Explain..
