• B. Gametes.
• C. Diploid Cells.

• E. Haploid Cells.
• F. Sperm Cells.

Answer: (D)

Verified step by step guidance

1. Understand the concept of nondisjunction: Nondisjunction is an error in cell division where chromosomes fail to separate properly during meiosis, leading to gametes with an abnormal number of chromosomes.
2. Identify the type of cells affected by nondisjunction: Nondisjunction during meiosis affects gametes, which are reproductive cells (sperm and egg cells).
3. Recognize the result of nondisjunction: Cells that have an abnormal number of chromosomes due to nondisjunction are referred to as aneuploid cells.
4. Differentiate between cell types: Somatic cells are body cells and are typically diploid, meaning they have two sets of chromosomes. Gametes are haploid, having one set of chromosomes, and are affected by nondisjunction.
5. Conclude the correct term: Aneuploid cells are the result of nondisjunction during meiosis, leading to gametes with extra or missing chromosomes.
