Question: 1 / 2700

If a sperm carries an X chromosome, what will the offspring be?

Male (XY)

Female (XX)

When a sperm carries an X chromosome, it can combine with an egg, which also contains an X chromosome. This fertilization results in a zygote with the combination of XX, which is the genetic makeup for a female offspring. In human sex determination, the mother always contributes an X chromosome, while the father's contribution can either be an X or a Y chromosome. If the sperm carries a Y chromosome, the offspring will be male (XY). Thus, when the sperm carries an X chromosome, the resultant offspring will always be female, leading to the conclusion that the correct answer is female (XX). This understanding of sexual differentiation is crucial in comprehending basic genetics and reproduction.
