Somatic cells undergo mitosis to produce genetically identical, diploid cells for growth and repair of body tissues. Cells in the seminiferous tubules in the testes of males and in the ovaries of females undergo meiosis to produce genetically different gametes for sexual reproduction. The gametes should have half the number of chromosomes as somatic cells so that the normal diploid number of chromosomes is restored at fertilisation. The gametes are genetically different to increase variation.

Meiosis - Wikipedia

In humans, male sex cells or spermatozoa sperm cells , are relatively motile. Female sex cells, called ova or eggs, are non-motile and much larger in comparison to the male gamete. Male and female sex cells are dramatically different from one another in size and shape. Male sperm resembles long, motile projectiles.

What type of cells undergo mitosis and meiosis?

It involves two rounds of division that ultimately result in four cells with only one copy of each paternal and maternal chromosome haploid. Additionally, prior to the division, genetic material from the paternal and maternal copies of each chromosome is crossed over , creating new combinations of code on each chromosome. Errors in meiosis resulting in aneuploidy an abnormal number of chromosomes are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.

Skip navigation. Meiosis, the process by which sexually reproducing organisms generate gametes sex cells , is an essential precondition for the normal formation of the embryo. As sexually-reproducing, diploid, multicellular eukaryotes, humans rely on meiosis to serve a number of important functions, including the promotion of genetic diversity and the creation of proper conditions for reproductive success.
