Consider a cell in which ALL of the homologous chromosomes experience nondisjunction during meiosis I. What would be the result of this event?

A. two diploid gametes and two non-viable gametes

B. one trisomic and three monosomic gametes

C. four aneuploid gametes

D. four monosomic gametes

E. one diploid, one aneuploid and two normal gametes

Solution

The answer is: C. four aneuploid gametes.

Nondisjunction during meiosis I would result in two n+1 cells and two n-1 cells.
