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 ).

WebThe realization that gametes are haploid, and must therefore be produced by a special type of cell division, came from an observation that was also among the first to suggest that chromosomes carry genetic information. In 1883, it was discovered that, whereas the fertilized egg of a roundworm contains four chromosomes, the nucleus of the egg and … WebMeiosis takes place in two consecutive cell divisions, called meiosis I and meiosis II. The two cell divisions result in four daughter cells, rather than the two daughter cells in mitosis. Each daughter cell has only half as many chromosomes as the parent cell.
