Which best describes the daughter cells produced in meiosis?

haploid

CORRECT

diploid

0

polyploidal

0

uniploid

0

Explanation

The answer is "haploid."

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.

They are both processes of cell division.

CORRECT

They both produce diploid daughter cells.

5

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?

96

0

48

CORRECT

192

0

none of these

0

Explanation

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

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

reproduce sexually

CORRECT

reproduce asexually

0

always produce 4 offspring

0

none of these

0

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.
