Effects of Nondisjunction
Nondisjunction results in an uneven distribution of chromosomes during cell replication. If nondisjunction occurs during meiosis I, the homologous chromosomes do not separate. If nondisjunction happens in meiosis II, sister chromatids do not separate. If a cell has a diploid number of six (2N = 6) before meiosis, how many chromosomes will be in each of the four daughter cells if one pair of chromosomes experiences nondisjunction during meiosis I?
