Meiosis provides for or leads to several different forms of genetic variation. for example:
a. it maximizes the mutation rate of dna
b. it minimizes the mutation rate of dna
c. it changes individual chromosomes through the process of "crossing over
d. it changes individual chromosomes through the process of nonrandom mutation
e. it doubles the number of chromosomes that were present at the beginning of the process

a. it maximizes the mutation rate of DNA

Explanation:

b. False

In fact, it maximizes due to the crossing over process that occurs in metaphase.

c. False

"Crossing over" doesn't change the chromosomes  individually, but in homologue pairs.

d. False

It is a random process

e. False

It doesn't double the number of chromosomes, but the genetic load
