If there are 20 chromatids in a cell at metaphase, how many chromosomes are there in each daughter cell following cytokinesis?
A
10
B
20
C
30
D
40
Explanation: 

Detailed explanation-1: -as a result, they will have 10 chromosomes immediately after cytokinesis, each of which is made up of a single chromatid.

Detailed explanation-2: -As centromeres join two chromatids hence 20 chromatids will contain 10 chromosomes each joining two chromatids.

Detailed explanation-3: -Hence, answer is ‘10 chromosomes’.

Detailed explanation-4: -The microtubules of the mitotic spindles are attached to it. Therefore, a cell having 20 centromeres will have 20 chromosomes.

Detailed explanation-5: -Complete answer: If an organism has 20 chromosomes, then the number of chromosomes the daughter cells have after mitosis is 20 because when a cell divides by the process of mitosis it produces two clone daughter cells having the same number of chromosomes (20) as the parent cell has.
