Question

Select all that apply. Meiosis _____. maintains chromosome number throughout generations causes genetic recombination is employed in maintenance causes genetic variation regulates environmental effects on the organism

Answer 1

Maintains chromosome number throughout generations.

Causes genetic recombination.

Causes genetic variation.

Step-by-step explanation:

Meiosis is a process in which egg cells create.

This process starts with a diploid cell with a full genetic charge and ends with two haploids, with half the amount of chromosomes. This is why maintains chromosome number throughout generations.

On prophase I of meiosis I, you have the crossing over.

This cross is what creates unique eggs always creating new combinations of the chromatids. This is why causes genetic recombination and this leads to genetic variation

Answer 2

• causes genetic recombination
• causes genetic variation

Explanation;

-Meiosis is a type of cell division which in which cells involved divides into four daughter cells which have half the number of chromosomes as the parent cells.

-Meiosis is important as it results to genetic variation in organisms through the process of cross over, in which genetic materials are exchanged by the homologous chromosomes, where segments of chromosome are exchanged by non-sister chromatids.

-Additionally, meiosis results to genetic recombination as a result of pairing of homologous chromosomes. This takes place when two molecules of DNA exchange their genetic material with one other.
