Claudia Salazar · Answer 1

Answer: option D - Four abnormal gametes

Explanation:

Nondisjunction occurs in the Anaphase phase of Meiosis I. It happens that at least ONE pair of homologous chromosomes FAIL to separate, resulting in two daughter cells having an EXTRA copy of one chromosome (e. g XXY) and two cells that are missing that chromosome (e. g XO).

Thus, Nondisjunction results in Four (4) abnormal gametes
