It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
WebCrossing over. The points where homologues cross over and exchange genetic material are chosen more or less at random, and they will be different in each cell that goes through meiosis. If meiosis happens many times, as in humans, crossovers will happen at many different points. Random orientation of homologue pairs. WebNov 15, 2024 · It is unknown how crossing over occurs, representing exchanges of DNA sequence data into chiasmata. The centromeres of the two sister chromatids join to produce a single kinetochore that binds microtubules when a homologous chromosome orients at the metaphase plate of meiosis I.
