Lab Review: Meiosis : Vindow Assign ÖLab Drill 5 of 5 What are the advantages of sexual reproduction by meiosis? Select all that apply. Crossing over that occurs during meiosis increase genetic variation. The fusion of a sperm and egg cell recombine genes increasing genetic diversity. Meiosis has more steps than mitosis so there are more checkpoints to make sure no errors in division have been made.. Meiosis results in diploid cells which leads to more genetic diversity

Answer 1

Answer:

Crossing over that occurs during meiosis increases genetic variation.

The fusion of egg and sperm cell recombines genes, increasing genetic diversity

Explanation:

Meiosis occurs in germ cells (egg and sperm). Meiosis along with fertilization is the sexual reproduction. During meiosis the crossing over of the chromosomes take place which leads to the genetic variation. During fertilization the sperm cell with genes from father and egg cell with genes from mother recombines will also increase the genetic diversity.

Meiosis results in haploid cells and mitosis results in diploid cells.

Mitosis and meiosis have similar cycles but some more complex cycles are in meiosis. Error free cell division is not an advantage of sexual reproduction. It is needed for all cell types. It does not leads to the genetic variation.
