With each member of the homologous pair attached to opposite poles of the cell, in the next phase, the microtubules can pull the homologous pair apart. The synaptonemal complex facilitates crossover between non-sister chromatids, which is observed as chiasmata along the length of the chromosome.

Each sister chromatid forms an individual kinetochore that attaches to microtubules from opposite poles. Regina Bailey. Following crossover, the synaptonemal complex breaks down and the cohesin connection between homologous pairs is also removed. Search term.

Updated November 20, From the time of puberty on, men make sex cells in the form of sperm cells continuously. The production of sex cells is called "gametogenesis. Some characteristics of organisms are so widespread and fundamental that it is sometimes difficult to remember that they evolved like other simpler traits.

Spermatozoa are also known as sperm and ova are also known as eggs. Haploid cells contain one set of chromosomes. Meiosis and mitosis share obvious cellular processes and it makes sense that meiosis evolved from mitosis.
