Occasionally during meiosis, chromosomes fail to separate normally into the four haploidcells, a phenomenon known as nondisjunction. WebApr 4, 2024 · If nondisjunction occurs during meiosis I, then four (4) daughter cells will have an incorrect number of chromosomes after meiosis. What is non-disjunction? Non-disjunction refers to the faulty separation of chromosomes during cell division (either meiosis or mitosis).

Webthe correct chromosome content. An interesting and striking solution to chromosome scattering in a large volume of oocyte cytoplasm was previously described in starﬁsh oocytes2–4. After NEBD, most of the chromosomes are out of reach of microtubule asters, the precursors of the meiotic spindle positioned at the animal pole of the oocyte.
