Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When do cells undergoing mitosis become haploid?
A
After Metaphase
B
After Cytokinesis
C
After Telophase
D
They are always diploid
Explanation: 

Detailed explanation-1: -Answer and Explanation: During telophase II of meiosis is when the daughter cells become haploid.

Detailed explanation-2: -Both diploid and haploid cells can undergo mitosis.

Detailed explanation-3: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Detailed explanation-4: -After Interphase I meiosis I occurs after Interphase I, where proteins are grown in G phase and chromosomes are replicated in S phase. Following this, four phases occur. Meiosis I is known as reductive division, as the cells are reduced from being diploid cells to being haploid cells.
