Chromosomes form tetrads during
WebDuring 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. During prophase II, sister chromatids align at the center of the cell in singular chromosome structures. WebApr 7, 2024 · The paired chromosomes are called a Homologous chromosome. The complex formed by this pair of the synapsed chromosome is known as a bivalent or tetrad. Pachytene: The bivalent chromosomes appear to be …

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.
