If we examine the diagrams of mitosis and meiosis, we see that in both cases, DNA replication occurs. Yet one process

ensures, mitosis, genetic continuity while the other, meiosis, facilitates genetic variation of daughter cells. Identify the choice that

does not explain genetic variation of daughter cells following meiosis.

A)

There is a reduction of the chromosome number from diploid to haploid

daughter cells.

B)

Meiosis is followed by fertilization: the union of gametes to create a

diploid zygote.

9

In metaphase I, each chromosome moves independently of the others: a

process called independent assortment.

D)

During prophase I, the homologous pairs of chromosomes often exchange

chromosome segments via crossing over.

Answer: B Meiosis is followed by fertilization: the union of gametes to create a diploid zygote.

Explanation: Fertilization does enhance genetic variation, but not of daughter cells. It enhances genetic variation in offspring. That means two parents could have four children with a variety of traits, such as different eye color or different heights. Meiosis enhances genetic variation through the reduction of chromosomes number, crossing over, and independent and random assortment of chromosomes.
