Question

What is the end result of meiosis?
A. Two diploid cells
B. Two haploid cells
C. Four diploid cells
D. Four haploid cells

Answer 1

Meiosis is 2 cell divisions.
The first reduces the chromosomes number in half.
The second is equal (mitosis) division.

So for humans:
A diploid cell has 46 chromosomes.
Before starting meiosis, the chromosomes replicate (becoming double).
So 46 double chromosomes separate into 2 cells of 23 double chromosomes each.

Since each cell contains 23 chromosomes, they are haploid.
But the chromosomes are double, so each cell divides, producing 4 cells, each with 23 single chromosomes.

The answer is D 4 haploid cells.

Answer 2

wow. thanks.

no problem
