Question

What are the three major differences between the events of mitosis and meiosis?

Answer 1

1) Mitosis consists one stage whereas miosis consists two stages.
2) Mitosis produced diploid cell whereas miosis produced haploid cell.
3) Mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.

Answer 2

Three major differences between the events of mitosis and meiosis are chromosome number, Genetic diversity and Phases (prophase, metaphase, anaphase, and telophase).

Mitosis and meiosis are both types of cell division that are involved in the reproduction and growth of organisms.

While there are many similarities between the two processes, there are also several key differences.

Here are three major differences between the events of mitosis and meiosis:

Chromosome number: Mitosis results in the formation of two identical daughter cells with the same chromosome number as the parent cell.

In contrast, meiosis results in the formation of four genetically unique daughter cells with half the chromosome number of the parent cell.

This reduction in chromosome number is essential for sexual reproduction to occur, as it allows for the fusion of two haploid gametes to form a diploid zygote.

Genetic diversity: Mitosis produces genetically identical daughter cells, whereas meiosis results in the creation of genetically diverse daughter cells.

During meiosis, genetic recombination occurs as a result of crossing-over between homologous chromosomes, which can result in new combinations of alleles.

Additionally, during meiosis I, the random orientation of homologous chromosomes at the metaphase plate and the subsequent segregation of these chromosomes into daughter cells can also result in genetic diversity.

Phases: The events of mitosis occur in four stages: prophase, metaphase, anaphase, and telophase.

Meiosis, on the other hand, involves two rounds of cell division, known as meiosis I and meiosis II.

Each of these rounds includes the same stages as mitosis, but with some differences, such as the pairing of homologous chromosomes in meiosis I and the separation of sister chromatids in meiosis II.

Additionally, meiosis I includes the formation of tetrads and crossing-over, which do not occur during mitosis.
