1. You find that a somatic cell has 23 chromosomes. Is this cell likely haploid or diploid. Explain how this could occur. (5) 2. Compare and contrast the haplontic and alternation of generations life cycles. (5)

The process in which two gametes unite is called sexual reproduction. It involves the swapping of genetic material during meiosis, which is a type of cell division that reduces the number of chromosomes by half. This process occurs in a series of life stages and events in sexually reproducing organisms. It can involve a single parent or two parents, with the latter having half the number of chromosomes and the former having twice the number of chromosomes. A diploid cell has twice the number of chromosomes, while a haploid cell has half the number of chromosomes. The development of haploid cells into gametes is called gametogenesis. Gametes are reproductive cells that unite to form an offspring. Other terms related to sexual reproduction include zygote, egg, sperm, fertilization, and haploid life cycle.
