Chromosomes form tetrads during
WebDuring DNA duplication in the S phase, each chromosome is replicated to produce two identical copies, called sister chromatids, that are held together at the centromere. The centrosomes, which are the structures that organize the microtubules of … 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.

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. desktop computers with hdmi portWebDuring prophase I, homologous chromosomes form tetrads along the center of the cell. Full chromosomes are pulled to each pole during anaphase I, resulting in two haploid cells at the end of meiosis I.
