Final answer:
A gamete is a specialized sex cell that carries half the number of chromosomes compared to regular body cells. In humans, the male gamete is called a sperm and the female gamete is called an egg or ovum.
Step-by-step explanation:
A gamete is a specialized sex cell that is produced during the process of meiosis, and it carries half the number of chromosomes compared to regular body cells. In humans, gametes have 23 chromosomes, which is the haploid number. The male gamete is called a sperm, while the female gamete is called an egg or ovum. At fertilization, one sperm combines with one egg to form a new individual.
