Answer:
Explanation:
Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.
The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with <u>half of the genetic material</u>. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.
They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.
Gametes have <u>half the number of chromosomes in body cells</u> and <u>choice A </u> is correct.
