Which process can be described as two cell divisions, genetic variation, and haploid cells? meiosis
The right answer is meiosis.
Meiosis is the process of double cell division allowing the formation of gametes, or sexual cells in eukaryotic organisms. It differs from mitosis, somatic cell division, which takes place only in a time. From a diploid mother cell, we obtain four haploid daughter cells with different genetic material.
* A first division of meiosis: the reduction division.
* A second division of meiosis: the equational division.
This process generates genetic diversity. It leads to the formation of haploid cells, designed to fuse with others, so as to obtain diploid cells after fertilization.
Ploidy – Wikipedia – Ploidy (/ ˈ p l ɔɪ d i /) is the number of complete sets of chromosomes in a cell, and hence the number of possible alleles for autosomal and pseudoautosomal genes. Somatic cells, tissues, and individual organisms can be described according to the number of sets of chromosomes present (the "ploidy level"): monoploid (1 set), diploid (2 sets), triploid (3 sets), tetraploid (4 setsIf a haploid cell undergoes mitosis, which is something certain types of plant and fungus do as part of their normal life cycles, the end result is two identical haploid cells (n→n). In meiosis, however, you start with a diploid cell that divides twice to produce four haploid cells.In meiosis, the chromosome or chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) during the first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes.
Mitosis Vs. Meiosis Help | The Cell Cycle, Cellular Growth – These new cells are created by mitosis, a process of cell division whereby a diploid parent cell gives rise to two identical diploid daughter cells. By contrast, the process of meiosis, which only occurs in germinal cells, produces non-identical haploid daughter cells. Meiosis ensures genetic variability by 'shuffling' our 'deck of genes'.MEIOSIS is the process that can be described as two cell divisions, genetic variation, and haploid cells.

The correct answer is A.The meiosis cell cycle has two main stages of division — Meiosis I and Meiosis II. The end result of meiosis is four haploid daughter cells that each contain different genetic information from each other and the parent cell. Click for more detail.
