Use the drop-down menus to complete the statements. <br><br> Meiosis involves cell divisions.
denpristay [2]

Answer:

Meiosis involves two cell divisions

Explanation:

Mitosis and meiosis are two kinds of cell divisions and one of the main differences between the two is that meiosis goes through <u>2 nuclear divisions</u>.

Meiosis has Meiosis I and Meiosis II division. In Meiosis I, the number of chromosomes in the daughter cells are only half of the parent cells. This is why it is called a reduction division, because the chromosomes will be reduced by half. In Meiosis II, the daughter cells will have the same number of chromosomes as the parent cells, which in this case is the daughter cells of meiosis I.

Weird fun fact: In Switzerland it is illegal to own just one guinea pig. Felt the need to mention that ^ Sorry, I know it has nothing to do with the question but i felt it was worth speaking of.
