How do sister chromatids form
WebDuring mitosis, duplicated sister chromatids are properly aligned at the metaphase plate of the mitotic spindle before being segregated into two daughter cells. This requires a complex process to ensure proper interactions between chromosomes and spindle microtubules. WebJul 3, 2024 · A tetrad is composed of four chromatids . As the two sister chromatids are aligned in close proximity to one another, one chromatid from the maternal chromosome can cross positions with a chromatid from the paternal chromosome. These crossed chromatids are called a chiasma.
