Makes diploid cells Makes genetically unique cells Happens throughout lifetime Involved in sexual reproduction Vocabulary Check What are homologous chromosomes? The word soma means “body.” How does this relate to the meanings of autosome and somatic cell? 2 Study Guide Unit 3 Resource Book McDougal Littell Biology CHAPTER 6 Meiosis.

Germ cells are the embryonic precursors of the gametes. They are set aside from the somatic cell lineages early in the development of most species. In the mouse. the germ cells, once they have formed, migrate through the tissues of the embryo to the gonad primordia (genital ridges), where they coassemble with somatic gonadal cells to form the sex cords. Cell Biology Study Guide In humans, gametes have 23 chromosomes. Diploid germ cells must undergo many rounds of cell division and create many new cells in order to produce haploid gametes. In normal sexual reproduction, two mature germ cells fuse to form a True In homo sapiens, the constitution of cells of the chromosome differs between the sexes, with females having two X chromosomes and males having one X chromosome and one Y chromosome. Meiosis, division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each with half the number of chromosomes of the original cell. The process of meiosis is characteristic of organisms that reproduce sexually and have a diploid set of chromosomes .
