Women sometimes develop benign tumors calledovarian teratomas or dermoid cysts in their ovaries.Such a tumor begins when a primary oocyte escapesfrom its prophase I arrest and finishes meiosis Iwithin the ovary. (Normally meiosis I does not finish until the primary oocyte is expelled from theovary upon ovulation.) The secondary oocyte thendevelops as if it were an embryo. Development isdisorganized, however, and results in a tumorcontaining differentiated diploid tissues, includingteeth, hair, bone, muscle, and nerve. If a dermoidcyst forms in a woman whose genotype is Aa, whatare the possible genotypes of the cyst, assuming norecombination?
