KollegeApply · Accepted Answer

the presence of a Y chromosome in a sperm Explanation: In humans, the ovum (egg) always carries an X chromosome, whereas the sperm carries either an X chromosome or a Y chromosome. If an X-bearing sperm fertilizes the ovum, the child will be XX (female). If a Y-bearing sperm fertilizes the ovum, the child will be XY (male). Therefore, the presence of a Y chromosome in the sperm determines the sex of the child.
