Question

males have both an x and a y chromosome. their gametes have either an x or a y chromosome. if a man has a son, which chromosome did he give his son? more information is needed

Explanation:

Step1: Understand chromosome inheritance

In humans, females have two X chromosomes (XX). Males have one X and one Y chromosome (XY).

Step2: Analyze gamete contribution

When having a child, the mother can only contribute an X chromosome (since her genotype is XX). The father can contribute either an X or a Y chromosome.

Step3: Determine chromosome for a son

For a child to be male (son), it must have the XY combination. Since the mother gives an X, the father must give the Y chromosome.

Answer:

The man gave his son the Y chromosome.
