LO 9.0 - PART 2 I
1. Who determines the gender of your baby the mother or the father, or both? Explain:

The one who determines the gender of a new baby is the father, since he is the carrier of the X and Y sex chromosomes.

Explanation:

The sex chromosomes X and Y are called sex determinants, since the sex of the offspring depends on them:

A mother can only provide her offspring with X chromosomes, while the father can provide both X and Y chromosomes, so he is the one who determines the sex of a new child. In this case, the possibility of having a male or female child will always be 50:50
