Q: Females are not influenced by the male sex hormone testosterone during embryonic development because they lack what?


Read this paragraph and choose the correct option from the provided answers:

Unlike males, females are not influenced by the male sex hormone testosterone during embryonic development. This is because they lack a Y chromosome. As a result, females do not develop male reproductive organs. By the third month of fetal development, most of the internal female organs have formed. Immature eggs also form in the ovary before birth. Whereas a mature male produces sperm throughout his life, a female produces all the eggs she will ever make before birth.

 Choices:

- x chromosome​

- m chromosome​

- z chromosome​

- y chromosome


A:
y chromosome
