Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A daughter cell that resulted from a mitotic division has 24 chromosomes. How many chromosomes did the parent cell have?

A	6
B	12
C	24
D	48

Explanation:

Detailed explanation-1: -Thus, the parent cell with 24 chromosomes after undergoing mitosis will form two daughter cells each with 24 chromosomes.

Detailed explanation-2: -Complete answer: If a cell has 24 chromosomes and it undergoes mitosis to create two cells, then the daughter cells also have 24 chromosomes each.

Detailed explanation-3: -If a cell has 24 chromosomes before cell division then daughter cell resulting from mitotic division will have 24 chromosomes while daughter cell resulting from the meiotic division will contain 12 chromosomes each.

Detailed explanation-4: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-5: -If the chromosome number for an organism is 22 before mitosis, then the chromosome number of each daughter cell after mitosis has taken place will also be 22. This is because mitosis produces two daughter cells that are genetically identical in terms of chromosome number and the genetic content of the chromosomes.
