Boys are to girls as _____ is to _____.

Question

Quizplus · Accepted Answer

The analogy between boys and girls is based on the XX/XY sex chromosome system in humans. Boys have an XY chromosome while girls have an XX chromosome. Therefore, the best analogy for this would be between two sex chromosome abnormalities. Klinefelter's syndrome is a genetic disorder where males have an extra X chromosome (XXY) and Turner's syndrome is a genetic disorder where females only have one X chromosome (X0). Thus, D is the correct answer as it uses Klinefelter's (males with an extra X chromosome) and Turner's (females with only one X chromosome) syndromes as the analogy for boys and girls.
