a
Normal X and fourth chromosome segregation.
b
The first number is the X chromosome nondisjunction progeny and the second is the fourth chromosome nondisjunction progeny. If there is only one number, it is for X chromosome nondisjunction. See materials and methods for calculating the frequency of nondisjunction.
