Solution
Failure of two homologous chromosomes to go to separate cells during meiosis leading to unequal number of chromosomes in the daughter cells is known as non-disjunction.
Explanation:
During meiosis, homologous chromosomes are supposed to segregate into different daughter cells. However, if they fail to separate (non-disjunction), it leads to gametes with either too many or too few chromosomes. This causes aneuploidy in the resulting offspring, which can lead to genetic disorders or developmental abnormalities.
