Correct Answer: B
Solution :
[b] Non-disjunction is the condition in which the separation of chromosome does not take place during cell division. In 44+XY gametes, there is non-separation of XY gene. It leads to the formation of sperm having genotypes, 22+XY and 22. In such condition, XY would be inherited together due to non-disjunction of XY-chromosome.You need to login to perform this action.
