Mitosis vs Meiosis

In mitosis, a cell with a diploid number of chromosomes (2n) undergoes cell division to produce two daughter cells, each with the same diploid number of chromosomes (2n).
Each daughter cell has the same genetic information as the original cell and can undergo interphase, replicating its DNA and growing, before dividing again through mitosis.
This process occurs in somatic cells, making up the bulk of the body, and allows for growth and development.
In meiosis, a cell with a diploid number of chromosomes (2n) undergoes cell division in two phases to produce four daughter cells, each with a haploid number of chromosomes (n).
In meiosis, the homologous pairs of chromosomes are split, resulting in genetic variation in the daughter cells.

Meiosis

Meiosis occurs in germ cells, such as those in the testes or ovaries.
The process of meiosis involves two phases: Meiosis One and Meiosis Two.
In Meiosis One, the diploid number of chromosomes is reduced to a haploid number, resulting in two cells with a haploid number of chromosomes.
In Meiosis Two, each of the two cells from Meiosis One undergoes a second round of cell division, resulting in four daughter cells, each with a haploid number of chromosomes.
Meiosis is not a cycle, and the resulting daughter cells are gametes (sperm or egg cells) that can be used in fertilization.

Key Differences

Mitosis produces two identical daughter cells, while meiosis produces four genetically varied daughter cells.
Mitosis occurs in somatic cells, while meiosis occurs in germ cells.
Mitosis allows for growth and development, while meiosis allows for genetic variation and the production of gametes.

This quiz covers the basics of mitosis and meiosis by comparing the two cell division processes. It reviews the diploid number of chromosomes in mitosis and how they are inherited from parents.
