Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A parent cell has 10 chromosomes. If one daughter cells after mitosis has 9 single chromosomes and the other has 9 single chromosomes and 1 double chromosome ____ when did the error occur?
A
prophase
B
metaphase
C
anaphase
D
telophase
Explanation: 

Detailed explanation-1: -10 chromosomes each. Mitotic division results in two daughter cells with an identical chromosomal number and genetic content to the parental cell.

Detailed explanation-2: -Hence, answer is ‘10 chromosomes’.

Detailed explanation-3: -Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

Detailed explanation-4: -For a cell with a diploid number of 10 (2n = 10), the two daughter cells that are produced after mitosis will contain ten chromosomes (identical to the parental cell).
