Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
Meiosis is required for the production of egg and sperm cells for sexual reproduction.
Meiosis starts with a parent cell that is diploid, which means it has two copies of each chromosome. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
During meiosis crossing over, and random segregation take place and are the reason for genetic variation in the offspring
Meisos involve halving the genetic material of a cell to form garments. The gametes of two parents fuse to form a zygote that6 returns the genetic material to normal ploidy so it can develop into offspring. The fusion of two gametes is called fertilization.
Late australopiths had an S-shaped spine that allowed for balance when standing. Shorter and less flexible toes made pushing off the ground much easier.
a fine, delicate membrane, the middle one of the three membranes or meninges that surround the brain and spinal cord, situated between the dura mater and the pia mater.
