Question

How many chromosomes shall be present in diploid cell at mitotic anaphase if it's egg cell has ten chromosomes
a.) 10
​​​​​​b.) 20
c.) 30
​​​​​​d.) 40

​​​​​​

Answer 1

Correct answer is option b) 20.
Explanation:

1. ​If the egg cell has 10 chromosomes (haploid 'n'), then the number of chromosomes present in diploid cell (2n) is 20.
2. The mitotic cell division is also known as equational division meaning that the number of chromosomes in each daughter cell is the same as the number of chromosomes present in the parent cell.
3. During anaphase, the sister chromatids are pulled towards the opposite poles by mitotic spindle fibres.
4. At each pole there will be 10 chromosomes i.e, 20 in the total cell.
