If we examine the diagrams of mitosis and meiosis, we see that in both cases, DNA replication occurs. Yet one process, mitosis, ensures 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.
Responses
A There is a reduction of the chromosome number from diploid to haploid daughter cells.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.Meiosis is followed by fertilization: the union of gametes to create a diploid zygote.
C In metaphase I, each chromosome moves independently of the others: a process called independent assortment.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.
