A genetic male has a hormone receptor deficiency that resulted in this person having a penis and both sets of internal sex organs. The most likely explanation for this case is that the person might
A) lack the Y chromosome.
B) have undergone plastic surgery.
C) have persistent Müllerian duct syndrome.
D) have testes that oversecreted anti-Müllerian hormone.
E) have Turner's syndrome.

Question

Quizplus · Accepted Answer

This person likely has persistent Müllerian duct syndrome, which is a genetic disorder where the Müllerian ducts, which normally break down in males, persist and develop into female internal sex organs. The presence of a penis suggests the individual has the SRY gene, which is located on the Y chromosome, ruling out option A. Plastic surgery would not result in the development of both male and female internal sex organs, making option B unlikely. Testes that oversecrete anti-Müllerian hormone would result in the degradation of female internal sex organs, ruling out option D. Turner's syndrome involves the absence of part or all of one of the X chromosomes, resulting in female traits developing in individuals with male chromosomes, making option E unlikely.
