In sexual reproduction, the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents. Fertilization and meiosis alternate in sexual life cycles. What happens between these two events depends upon the organism. The process of meiosis, the division of the contents of the nucleus that divides the chromosomes among gametes, reduces the chromosome number by half, while fertilization, the joining of two haploid gametes, restores the diploid condition. There are three main categories of life cycles in eukaryotic organisms: diploid-dominant, haploid-dominant, and alternation of generations

To regenerate damaged tissue
Explanation:
Stem cells can be pluripotent, totipotent or multipotent depending on where they are sourced. This means that they are capable of differentiating into a wide variety of cells. Stem cells can, therefore, be harvested and induced to differentiate into cells or tissues that are intended to be repaired.
