Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Sarah inherits a new mutation from her mother. During which stage of cell division did the mutation likely occur?
A
Prophase of Mitosis
B
Prophase 1 of Meiosis
C
Telophase of Mitosis
D
Cytokinesis of Meiosis 1
Explanation: 

Detailed explanation-1: -1 Answer. if it is a gene mutation then it is during the S phase, and if it is a chromosome mutation, then during metaphase or anaphase.

Detailed explanation-2: -Meiosis I, the first meiotic division, begins with prophase I. During prophase I, the complex of DNA and protein known as chromatin condenses to form chromosomes. The pairs of replicated chromosomes are known as sister chromatids, and they remain joined at a central point called the centromere.

Detailed explanation-3: -The third stage of the cell cycle is called cytokinesis. During this stage, the cytoplasm of the cell divides to form two cells. These two cells are called daughter cells. The new daughter cells are exactly the same as each other.

Detailed explanation-4: -When do genetic mutations happen? Genetic mutations occur during cell division when your cells divide and replicate.
