GENERAL KNOWLEDGE

Detailed explanation-1: -During sexual reproduction, specialized haploid cells from two individuals join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores (Figure 11.1. 1b). The third life-cycle type, employed by some algae and all plants, is called alternation of generations.

Detailed explanation-2: -Sexual reproduction involves both meiosis and fusion of male and female haploid gametes. It is the production of new living organisms by combining genetic information from two individuals of different sexes.

Detailed explanation-3: -Meiosis is a process that occurs in sex cells, such as sperm and egg cells in the human body, to make more of them. In the primordial germ cells of males and females, meiosis takes place in the testes and ovaries, respectively.

Detailed explanation-4: -Asexual reproduction involves one parent and produces offspring that are genetically identical to each other and to the parent. Sexual reproduction involves two parents and produces offspring that are genetically unique.
