Quick Answer: Does independent assortment occur during mitosis or meiosis Why?

Does independent assortment occur in mitosis and meiosis?

When Does Independent Assortment Occur? Independent assortment occurs during the process of meiosis. Meiosis is similar to mitosis, only the final product is gamete cells.

Why does independent assortment occur in mitosis?

The independent assortment of chromosomes is a result of the independent division of chromosomes into separate gametes. Then, crossing over takes place where genes on each chromosome are rearranged. The Law of Independent Assortment discusses the random genetic inheritance from both parents.

Why does independent assortment occur in meiosis but not mitosis?

The daughter cells produced by mitosis are identical, whereas the daughter cells produced by meiosis are different because crossing over has occurred. The events that occur in meiosis but not mitosis include homologous chromosomes pairing up, crossing over, and lining up along the metaphase plate in tetrads.

Does independent assortment occur in meiosis I or meiosis II?

Homologous chromosomes separate in meiosis I. Sister chromatids separate in meiosis II. Independent assortment of genes is due to the random orientation of pairs of homologous chromosomes in meiosis I. … Crossing over produces new combinations of alleles on the chromosomes of the haploid cells.

How does Independent Assortment relate to meiosis?

The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. … During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.

What is the difference between mitosis and meiosis?

Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.

How does Independent Assortment work?

The Principle of Independent Assortment describes how different genes independently separate from one another when reproductive cells develop. … During meiosis, the pairs of homologous chromosome are divided in half to form haploid cells, and this separation, or assortment, of homologous chromosomes is random.

How does the principle of independent assortment apply to chromosomes?

The principle of independent assortment applies to chromosomes because it is the chromosomes that sort independently, not the genes. … The principle of independent assortment states that genes for different traits can segregate independently during the formation of gametes.

Why are the processes of crossing over and independent assortment important events during meiosis?

Genetic variation is increased by meiosis

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.

Which process normally occurs during meiosis but not during mitosis?

In meiosis , synapsis ( Pairing of homologous chromosome ) , Crossing over ( exchange of chromosomal segment between nos sister chromatids ) occurs which does not occur in mitosis.

Why does meiosis result in greater genetic diversity than mitosis?

Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. Meiosis creates new combinations of genetic material in each of the four daughter cells. That is why meiosis results in greater genetic diversity than mitosis.
