Chromosomes & Meiosis Test Day Quick Review

Which of the following best defines an autosome?

• A chromosome that does things automatically

• A chromosome that is least common in a human set of chromosomes

• A non-sex chromosome

• A sex-determining chromosome

Each identical side of a replicated chromosome is a

• centromere

• chromatin

• centriole

• chromatid

Unlike mitosis, meiosis in male mammals results in the formation of

• one haploid gamete
• three diploid gametes
• four diploid gametes
• four haploid gametes

Identify the phase.

• Anaphase I

• Metaphase II

• Prophase I

• Anaphase II

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids

• condensation and segregation of alleles

• mutationin which the DNA content of the gene is altered

• crossing - over in which alleles on non-sister chromatids are exchanged

Crossing over, independent assortment of chromosomes, and random fertilization helps promote

• meiosis

• genetic variation

• DNA replication

• mitosis

During which phase in the cell cycle is DNA replicated?

• G1

• S

• G2

• Mitosis

The end of mitosis results in

• 2 cells that are identical
• 4 cells that are identical
• 2 cells that are not identical
• 4 cells that are not identical
