Question

if pollen Mother cell has 20 chromosomes what is the number of chromosomes in anaphase 1 and anaphase 2

Answer 1

Answer:

answer in explanation chec it out

Explanation:

Egg cell is haploid. If egg cell has 10 chromosomes, this means n = 10.

Hence, chromosomes in diploid cell will be 2n i.e. 2x10 = 20.

At mitotic anaphase, the cell will be having double the number of chromosomes of the diploid cell, half of which will be at one pole and other half will be at opposite pole because later, this cell will divide into two daughter cells having same number of chromosomes as the parent cell i.e. 10.

Therefore, at mitotic anaphase, chromosomes in the diploid cell = 2x20 = 40

So, the correct answer is '40'.
