WebIn mitosis, homologous chromosomes line up end-to-end so that when they divide, each daughter cell receives a sister chromatid from both members of the homologous pair. The synaptonemal complex, a lattice of proteins between the homologous chromosomes, first forms at specific locations and then spreads to cover the entire length of the … Webd. The chromosomes randomly align during prophase I at the equator, and separation of bivalent chromosomes occur during anaphase I of meiosis I. Similarly, separation of homologous chromosomes occurs at metaphase II of meiosis II. At the end of meiosis II, four different gametic combinations are produced, each containing a diploid set of ...

Genes, the functional units of chromosomes, determine specific characteristics by coding for specific proteins. Traits are the variations of those characteristics.

WebThen, the homologous pairs line up at the equator of the cell and are pulled apart. This process is called crossing over, and it is responsible for the genetic variation in the daughter cells. During meiosis II, the sister chromatids are separated and pulled to opposite poles of the cell, in a similar way to the process of mitosis. http://www.biologyreference.com/Ma-Mo/Meiosis.html
