The event called "crossing over" in meiosis results in
A)greater genetic variety in sex cells and thus in embryos.
B)less genetic variety in sex cells.
C)greater vitality of sex cells making them more active.
D)a change in the gender (sex)of the embryo.
E)irreversible mutations.

Accepted Answer

Crossing over in meiosis is the process where genetic material is exchanged between paired homologous chromosomes. This results in a greater genetic variety in the resulting sex cells, which can lead to greater genetic diversity in embryos during fertilization.
