Meiosis video Quiz

What is the purpose of meiosis?

• Produce gametes

• Produce somatic cells

• Produce stem cells

• Produce muscle cells

Answer explanation

The purpose of meiosis is to produce gametes, which are reproductive cells involved in sexual reproduction.

How many stages of cell division are there in meiosis?

• One

• Two

• Three

• Four

Answer explanation

Meiosis consists of two stages of cell division: meiosis I and meiosis II. This process is responsible for the formation of gametes and genetic diversity.

What happens during prophase 1 of meiosis?

• Chromosomes line up at the equator

• Homologous chromosomes separate

• Nuclear membrane disappears

• Spindle fibers disappear

Answer explanation

During prophase 1 of meiosis, the nuclear membrane disappears, preparing for the separation of homologous chromosomes.

What is a tetrad in meiosis?

• A group of four alleles

• A group of four homologous chromosomes

• A group of four spindle fibers

• A group of four sister chromatids in paired homologous chromosomes

Answer explanation

A tetrad in meiosis refers to a group of four sister chromatids in paired homologous chromosomes, which is the correct choice.

What is the result of crossing over in meiosis?

• Identical sister chromatids

• No genetic variety

• Different gene combinations

• Identical gene combinations

Answer explanation

Crossing over in meiosis results in different gene combinations, leading to genetic variety.

How many haploid daughter cells are produced at the end of meiosis 1?

• One

• Four

• Two

• Three

Answer explanation

At the end of meiosis 1, two haploid daughter cells are produced. This is because the cell undergoes two rounds of division, resulting in the separation of homologous chromosomes.

What happens during metaphase 2 of meiosis?

• Chromosomes line up at the equator

• Homologous chromosomes separate

• Spindle fibers disappear

• Nuclear membrane disappears

Answer explanation

During metaphase 2 of meiosis, chromosomes line up at the equator.

What is the outcome of the second division of meiosis?

• Two genetically identical diploid cells

• Four genetically identical diploid cells

• Four genetically different haploid cells

• Two genetically different haploid cells

Answer explanation

The outcome of the second division of meiosis is the formation of four genetically different haploid cells.

What happens during anaphase 2 of meiosis?

• Chromosomes move to opposite poles

• Spindle fibers appear

• Nuclear membrane reappears

• Homologous chromosomes pair up

Answer explanation

During anaphase 2 of meiosis, chromosomes move to opposite poles, separating and preparing for cell division.

What is the main outcome of meiosis?

• Production of genetically identical cells

• Production of genetically different haploid cells

• Duplication of DNA

• Separation of sister chromatids

Answer explanation

The main outcome of meiosis is the production of genetically different haploid cells.
