16-10 Cross Over & Independent/Random Assortment in Meiosis (Cambridge AS A Level Biology, 9700)
มุมมอง 99921 วันที่ผ่านมา
2 important processes in meiosis helps to produce genetically different gametes. 1. 4:50 Cross-over during Prophase 1. When synapsis happens, the homologous chromosomes pair up, causing the chromatids to overlap and allow the exchange of genetic material at the chiasma (point of overlap). This allows for new allele combinations to be made. 2. 9:25 Independent/Random Assortment in Metaphase 2. T...
