An 18-year-old woman consulted a physician because of her failureto initiate menses. She had experienced normal breast developmentat age 13, but no pubic or axillary hair had ever appeared. Her heightwas 5 feet 6 inches, weight 119 pounds, blood pressure 110/70,and pulse 60 beats/minute. Her physical examination confirmedthe presence of well-developed breasts and the external genitaliaof a normal female. However, the vagina ended in a blind pouch,and there was no evidence of a cervix, ovaries, or a uterus. Withinthe inguinal area, the examining physician could palpate a small,spherical mass on each side. Is this patient’s genotype most likelyXX, XO, or XY? Explain why the genotype you selected is consistent with the manifestations

Question
An 18-year-old woman consulted a physician because of her failure
to initiate menses. She had experienced normal breast development
at age 13, but no pubic or axillary hair had ever appeared. Her height
was 5 feet 6 inches, weight 119 pounds, blood pressure 110/70,
and pulse 60 beats/minute. Her physical examination confirmed
the presence of well-developed breasts and the external genitalia
of a normal female. However, the vagina ended in a blind pouch,
and there was no evidence of a cervix, ovaries, or a uterus. Within
the inguinal area, the examining physician could palpate a small,
spherical mass on each side. Is this patient’s genotype most likely
XX, XO, or XY? Explain why the genotype you selected is consistent with the manifestations
