WebNearly all animals have a diploid-dominant life cycle in which the only haploid cells are the gametes. Early in the development of an animal embryo, special diploid cells, called germ cells, are made in the gonads (testes and ovaries).Germ cells can divide by mitosis to make more germ cells, but some of them undergo meiosis, making haploid gametes (sperm and … WebDuring meiosis I, homologous chromosomes pair up with each other.

WebCells undergo through meiosis I to meiosis II without the replication of the genetic material. It is important to note that the cells that undergo meiosis II are the daughter cells produced during meiosis I. Meiosis II is shorter than meiosis I but still is divided into four stages: prophase II, metaphase II, anaphase II, and telophase II.
