What is the main purpose of meiosis?

1 pts

volume_mute

Meiosis is a specialized type of cell division that differs fundamentally from mitosis in its purpose and outcome.

What is the main purpose of meiosis?

To produce four haploid cells (gametes) for sexual reproduction

To repair damaged DNA in somatic cells

To allow prokaryotic cells to replicate

To produce two genetically identical diploid cells for growth and repair

Correct Answer

Explanation

How many divisions occur during meiosis, and how many daughter cells are produced?

1 pts

volume_mute

Unlike mitosis (which involves one division), meiosis proceeds through two sequential divisions.

How many daughter cells does meiosis ultimately produce?

Two divisions producing two cells

One division producing two cells

One division producing four cells

Two divisions producing four cells

Correct Answer

Explanation

What is the chromosome number of the gametes produced by meiosis compared to the parent cell?

1 pts

volume_mute

A key outcome of meiosis is the change in chromosome number in the resulting cells.

If the parent cell is diploid (2n), what is the chromosome number of each gamete produced?

Twice the diploid number (4n)

The same diploid number (2n)

A random number of chromosomes

Half the diploid number - haploid (n)

Correct Answer

Explanation

The exchange of genetic material between homologous chromosomes during meiosis

1 pts

volume_mute

During the first meiotic division, homologous chromosomes pair up. While paired, they may exchange segments of genetic material.

This exchange process is called (1).

How many pairs of chromosomes do humans have?

1 pts

volume_mute

The number of chromosomal pairs varies by species. The actual number of pairs depends on the species involved.

46 pairs

16 pairs

32 pairs

Please drag and drop the options to sort them

Arrange the following events of meiosis in the correct order from first to last.

Second meiotic division begins in both cells

Four haploid gametes are produced

Sister chromatids separate

First meiotic division - homologous pairs separate into two cells

Homologous chromosomes pair up; crossover may occur

1 pts

volume_mute

Select ALL statements that are true of meiosis but NOT of mitosis.

Results in haploid (n) cells

Used for growth and tissue repair

Involves crossover between homologous chromosomes

Produces four daughter cells

Involves two successive divisions

Correct Answer

Explanation

Why is crossover important in meiosis?

1 pts

volume_mute

Crossover is a unique feature of meiosis that does not occur during mitosis. Why is it biologically significant?

It ensures daughter cells are genetically identical to the parent

It generates new combinations of alleles, increasing genetic variation among offspring

It allows cells to skip the second meiotic division

It prevents chromosomes from being damaged during cell division
