Example Question #1 : Understand Meiosis

What is meiosis?

Possible Answers:

a process of cell division in sexual reproduction

a process of cell division for replacement of cells

a process of cell division in asexual reproduction

a process of cell division that happens before mitosis

Correct answer:

a process of cell division in sexual reproduction

Explanation:

Meiosis is a process where a single cell divides twice to produce four sex cells containing half the original amount of genetic information. These daughter cells are all genetically identical. Since the four daughter cells only have half the number of chromosomes of the parent cell, they are considered haploid. The main purpose of meiosis is to produce sex cells which are later combined in sexual reproduction to increase genetic variation. Meiosis is where crossover and recombination can take place, further increasing the genetic variation of daughter cells.

Some key differences between meiosis and mitosis are: Mitosis involves the division of body cells, while meiosis involves the division of sex cells. Two daughter cells are produced in mitosis, while four are produced in meiosis. Mitosis daughter cells are diploid, but meiosis daughter cells are haploid. Meiosis creates more genetic variation than mitosis.

 

Example Question #2 : Understand Meiosis

What are produced from the process of meiosis?

Possible Answers:

two genetically different daughter cells

four genetically identical daughter cells

four genetically different daughter cells

two genetically identical daughter cells

Correct answer:

four genetically different daughter cells

Explanation:

The answer is "four genetically different daughter cells"

Example Question #3 : Understand Meiosis

Which best describes the daughter cells produced in meiosis?

Possible Answers:

diploid

haploid

haploid

Explanation:

The answer is "haploid."

They are both processes of cell division.

They are both used to create replacement body cells.

They both produce diploid daughter cells.

They are both processes of cell division.

Explanation:

The answer is "they are both processes of cell division."

Example Question #5 : Meiosis And Mitosis

Screen shot 2020 06 10 at 1.14.54 pm

According to this diagram, organisms that use meiosis to produce sex cells:

Possible Answers:

reproduce asexually

always produce 4 offspring

reproduce sexually

none of these

Correct answer:

reproduce sexually

Explanation:

The answer is "reproduce sexually" because they have a maternal and paternal chromosome from their parents, and produce haploid cells to provide half the genetic material for offspring.

Meiosis is a process where a single cell divides twice to produce four sex cells containing half the original amount of genetic information. These daughter cells are all genetically identical. Since the four daughter cells only have half the number of chromosomes of the parent cell, they are considered haploid.

somatic cells

blood cells

Correct answer:

Explanation:

The answer is "egg cells."

Example Question #6 : Understand Meiosis

A species of minnow has 96 chromosomes. How many chromosomes would be present in a daughter cell after the process of meiosis is completed in a one minnow cell?

Possible Answers:

192

48

none of these

96

Correct answer:

48

Explanation:

The answer is "48" because meiosis produces daughter cells with half as many chromosomes.
