33. meiosis and sexual reproduction each lead to variation in the genetic make-up of every person.
with your group, explain how meiotic events, as well as the random fertilization of eggs and
sperm, together lead to this genetic variation.

The genetic data present in the DNA of an organism is different from the parent DNAs.  

Explanation:

The large number of varied combination of genes are produced through the reproduction procedure. In the process of Meiosis, gametes are produced in the form of sperms and eggs. The alleles of gametes get separated and units randomly with fertilization of gametes.

In this way reproduction causes variation in genes. In humans some variations of genes are - the skin and hair color. This variation leads to a trait of an organism.

the pic attached shows the stages of mitosis. hope it !

your the dumbest b**tch ive ever seen
