Meiosis is a type of cell division that ensures the production of sex cells, or gametes, with half the number of chromosomes compared to the original cell. The main purpose of meiosis is to facilitate sexual reproduction by creating genetic diversity through recombination and segregation of chromosomes.
During meiosis, a single diploid cell undergoes two rounds of division to produce four haploid cells. This process allows for the combination of genetic material from two parents during fertilization, resulting in offspring that have a unique set of genes. This genetic variation is crucial for evolution and adaptation in changing environments.
In summary, meiosis plays an essential role in producing gametes, which are vital for sexual reproduction, while also contributing to genetic diversity within a population.
