Number of chromosomes in germ cells

WebIf a chromosomal segment breaks off and is not rejoined, it may be lost entirely in the gametes or somatic cells that derive, respectively, from meiosis or mitosis. Such a loss is called a deletion. In other instances, the broken-off segment may rejoin its chromosome but with its position inverted 180 ; such inversions can alter the sequence of genetic … WebMeiosis is the unique division of germ cells resulting in the recombination of the maternal and paternal genomes and the production of haploid gametes.

Germ cells produce gametes and are the only cells that can undergo meiosis as well as mitosis. These cells are sometimes said to be immortal because they are the link between generations. Somatic cells are all the other cells that form the building blocks of the body and they only divide by mitosis. The lineage of germ cells is called the germline.
