Solution and Explanation
Sex determination in humans is based on the presence of sex chromosomes. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome determines maleness, while its absence results in femaleness. The sex chromosome from the father determines the sex of the offspring.
