What happens to the number of chromosomes during meiosis? The number of chromosomes in the daughter cells becomes double that of the
parent cell.
The number of chromosomes in the daughter cells remains the same as that of
the parent cell.
The number of chromosomes in the daughter cells becomes one-fourth that of
the parent cell
The number of chromosomes in the daughter cells becomes half that of the
parent cell.

The number of chromosomes in daughter cell becomes one-forth that of the parent cell

Explanation:

The number of chromosomes in the daughter cell becomes one-forth that of the parent cell. It is because four daughter cells are produced in meiosis. So one daughter cell recieve one-forth that of the parent cell.

answer; i believe the answer is (polygenic inheritance;

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
