Nondisjunction is an error in meiosis that results in non-separation of chr chromosomes es during anaphase. Nondisjunction can occur during anaphase I or anaphase II of meiosis Which of the following correctly describes the gametes that will form as a result of nondisjunction during anaphase II in a human male? a. Four sperm with 22 chromosomes b. Four sperm with 24 chromosomes c. Two sperm with 23 chromosomes, one sperm with 22 chromosomes, and one sperm with 24 chromosomes d. Two sperm with 24 chromosomes and two sperm with 22 chromosomes

The correct answer is **c. Two sperm with 23 chromosomes, one sperm with 22 chromosomes, and one sperm with 24 chromosomes.**<br /><br />Here's why:<br /><br />* **Meiosis I:** Meiosis I proceeds normally. Homologous chromosomes separate, resulting in two cells, each with 23 chromosomes (each chromosome consisting of two sister chromatids).<br /><br />* **Meiosis II (with nondisjunction):** In one of these two cells, during anaphase II, the sister chromatids of one chromosome fail to separate. This means one daughter cell receives both sister chromatids (making 24 chromosomes), and the other daughter cell receives none of those chromatids (making 22 chromosomes). The other cell from meiosis I completes meiosis II normally, producing two gametes with 23 chromosomes each.<br /><br />* **Final Result:** Therefore, after both cells complete meiosis II, you end up with:<br /> * Two sperm with 23 chromosomes (from the cell where meiosis II occurred normally)<br /> * One sperm with 22 chromosomes (from the nondisjunction event)<br /> * One sperm with 24 chromosomes (from the nondisjunction event)<br />
