Which process can be described as two cell divisions, genetic variation, and haploid cells?
a) meiosis
b) mitosis
c) binary fission
d) fertilization

Answer;

A. Meiosis

The process that can be described as two cell divisions, genetic variation, and haploid cells.

Explanation;

Meiosis is a type of cell division that is responsible for the production of gamete cells. the parent cell divides to yield four daughter cells that are haploid, have only one set of each chromosome.

Two cell divisions because it takes place in two stages meiosis I and meiosis II.

Genetic variation; the type of cell division is characterized by genetic variation due to the process of cross over and recombination that allows exchange of genetic materials.

Haploid cells; because the daughter cells produced are haploid; that is they have half the number of chromosomes as the parent.

the correct option is option d

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.
