Meiosis increases the chance of fertilization because it produces 4 daughter cells

b)

Meiosis results in offspring with genotypes that are not exact copies of the parents

c)

Meiosis allows chromosomes to exchange genetic material through crossing over

d)

Mitosis produces 2 diploid cells, while meiosis produces 4 haploid cells

b)

Mitosis produces 4 diploid cells, while meiosis produces 2 haploid cells

c)

Mitosis produces 2 haploid cells, while meiosis produces 4 diploid cells

d)

Mitosis produces 4 haploid cells, while meiosis produces 2 diploid cells

9.

The diagram above shows a process that occurs during meiosis. Which of the following best explains how this process contributes to genetic variation?

a)

Crossing over of homologous chromosomes allows exchange of genes

b)

Independent assortment results in a random number of chromosomes from each parent

c)

Fertilization results in offspring that have a combination of traits from each parent

d)

Mutations result in the emergence of new traits in a population

10.

In meiosis, chromatids might sometimes separate incorrectly, resulting in gametes that have 22 or 24 chromosomes, instead of 23. Which process is being described in this scenario?
