Male Heterogamety
Explanation
Solution
In male heterogamety, such as in humans (XY sex determination system), males possess one X and one Y chromosome (XY), while females have two X chromosomes (XX). This means that the male determines the sex of the offspring by passing either an X or a Y chromosome, while the female always contributes an X chromosome.
