Cell Division

Which of the following is a difference between sexual and asexual reproduction?

• regeneration is exclusive to sexual reproduction

• asexual reproduction occurs only in haploid organisms

• sexual reproduction includes the development of unfertilized eggs

• sexual reproduction is more likely to increase the chance of genetic variation than is asexual reproduction

When a eukaryotic cell is not dividing, its genetic material can be found in the form of very long thin fibers called

• chromatin

• chromosomes

• the nucleolus

• RNA

During prophase of mitosis, each chromosome of a eukaryotic cell consists of a pair of identical structures called

• chromatid

• sister chromosomes

• DNA transcript

• sister chromatids
