Answer: The statement "The production of gametes is known as gametogenesis" is true about sexual reproduction.
Therefore, the correct answer is B. The production of gametes is known as gametogenesis.
Explanation: The first claim—that the human life cycle exclusively includes gametes—is untrue. The stage in which the cells contain half as many chromosomes as the parent cell is known as the haploid phase. Gametes are haploid cells, and meiosis, the process by which gametes are produced is another haploid phase of the human life cycle.
The second claim—that gametogenesis is the process by which gametes are produced—is accurate. In sexually reproducing organisms, the production of haploid gametes (eggs and sperm) is known as gametogenesis.
A fertilized egg is referred to as a zygote, which is also true of the third claim. When a sperm cell and an egg cell combine to form a zygote during fertilization, a diploid cell with the full complement of chromosomes is created.
The right response is therefore C. Gametogenesis is the process of creating gametes, and a zygote is a fertilized egg.
