Meiosis is a kind of cell division that describes how germ cells divide, resulting in the fission of two nuclei.
This form of cell division happens during reproduction when one cell divides into four haploid daughter cells.
Each newly formed cell has a unique chromosomal mix and only half the genetic material of the parent cell.
Consequences without meiosis:
Without meiosis, the number of chromosomes will not remain constant in a species across generations and will be duplicated every time after sexual reproduction.
An organism will not be able to reproduce effectively by sexual reproduction without meiosis.
