Question

DNA replication occurs before meiosis I but not before meiosis II. Why is that important?

0.It results in uneven division of the cytoplasm.

1.It results in uneven division of the cytoplasm.

2.It results in increased genetic diversity for the species.

3.It results in increased genetic diversity for the species.

4.It results in offspring that are genetically identical to the parents.

5.It results in offspring that are genetically identical to the parents.

6.It results in daughter cells with the haploid number of chromosomes.

Please help we are doing a test aint i have no idea

Answer 1

It results in daughter cells with the haploid number of chromosomes.

Step-by-step explanation:

Before meiosis, DNA replication occurs in the diploid parent cells.

Then, the first round of meiosis (i.e. cell division) occurs. This creates two daughter cells, each with a diploid genome. Then, a second round of meiosis occurs in each cell, pulling apart the chromosomes and creating two haploid cells from each cell, resulting in a total of four haploid cells.

When these haploid cells participate in fertilization, they fuse with another haploid cell (e.g. an egg and sperm are both haploid and fuse) to make the zygote. This restores the diploid state so that every cell in the new organism is diploid.
