WebAt the end of prophase I, the pairs are held together only at the chiasmata ( [link]) and are called tetrads because the four sister chromatids of each pair of homologous chromosomes are now visible. The crossover events are the first source of genetic variation in the nuclei produced by meiosis. http://pressbooks-dev.oer.hawaii.edu/biology/chapter/the-process-of-meiosis/ highs mids lows explained

WebThe meiosis occurs in two stages meiosis I and meiosis II. Meiosis I is characterised by the pairing of homologous chromosomes, crossing over between homologous chromosomes and separation of homologous chromosomes, so that each daughter cell produced after meiosis I have one-half the chromosome number as compared to the parent cell.
