Question

Consider the abbreviated model of meiosis. The end result of meiosis should be the production of four haploid gametes. In this example, an error has taken place. Describe and name this error.

A) Nondisjunction of sister chromatids during meiosis II. Sister chromatids fail to separate.
B) Translocation of sister chromatids during meiosis II. One chromatid is translocated into incorrect cell.
C) Separation mutation during meiosis I. Resulting gametes in meiosis II have incorrect chromosome number at end of meiosis.
D) Replication error during meiosis I. Results of mutation show during meiosis II as incorrect chromosome number in two gametes.

Answer 1

The answer is A.

Step-by-step explanation:

Nondisjunction of sister chromatids during meiosis II. Sister chromatids fail to separate.
