Meiosis only occurs in sex cells
WebThe diploid multicellular stage is called the _____ because it produces haploid spores by meiosis, each of which will give rise to a whole new gametophyte. Meiosis only occurs in diploid cells. 5. Animals produce three types of cell. These are diploid _____ (body) cells, and haploid sex cells or _____ (sperm and egg). WebThey are caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis. The risk of nondisjunction increases with the age of the parents. Nondisjunction can occur during either meiosis I or II, with different results ( Figure 7.8 ).
