Question

5. Which of the following statements best explains the role of meiosis in reproduction?

Meiosis allows chromosomes to exchange genetic material through crossing over.
Meiosis makes it possible for a zygote to have the correct number of chromosomes.
Meiosis increases the chances of fertilization because it produces four daughter cells.
Meiosis results in offspring with genotypes that are not exact copies of the parents.

Answer 1

The correct answer is: Meiosis makes it possible for a zygote to have the correct number of chromosomes.

Step-by-step explanation:

Meiosis is a type of cell division used by reproducing organisms to produce the gametes (as sperm or egg cells). It has two rounds of division that results in four cells with one copy of each chromosome.

Before the division, genetic material from each chromosome is crossed over and creates new combinations of code on each chromosome. During fertilization, the cells produced by meiosis will conjoin to create a cell with copies of each chromosome again, the zygote.

Answer 2

Hello!

The answer is Meiosis allows chromosomes to exchange genetic material through crossing over.

Step-by-step explanation:

Meiosis:

Meiosis, also known as reduction division, is the type of cell division that produces four gametes by reducing the number of chromosomes in each daughter cell.

Meiosis occurs in the germ cells and is required for reproduction. Unlike Mitosis, which produces copies of the parent genetic material, meiosis is responsible for producing variations in the offspring DNA. Meiosis allows the crossing over which is the exchange of genetic material between chromosomes that will ultimately end up in separate daughter cells. This process will produce four gametes with a varied set of genes.
