Answer to Question 1

ANS: B
The mesonephric ducts evolve into the male genital tract due to the influence of testosterone in the 7th or 8th week of gestation. A gonad is the first reproductive structure formed. Production of spermatozoa doesn't occur until puberty. The growth of external genitalia does not begin until the 12th week of gestation.

Answer to Question 2

ANS: D
It takes about 8 weeks of development before the reproductive system becomes differentiated as male or female, but external genitalia are not visible until after 12 weeks.
