Mitosis Regents Questions

Front

What is the end result of meiosis?

Back

4 unique daughter cells.

Front

How many chromosomes do gametes (sex cells) contain?

Back

23 chromosomes (haploid).

Front

What is the primary function of meiosis?

Back

Reduces the number of chromosomes by one half and produces unique sex cells.

Front

What is a centromere?

Back

The region of a chromosome where the two sister chromatids are joined.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells contain one set of chromosomes (23), while diploid cells contain two sets (46).

Front

What is genetic variation?

Back

Differences in DNA among individuals, which can result from meiosis and sexual reproduction.

Front

What is the significance of meiosis in sexual reproduction?

Back

It ensures that offspring have the correct number of chromosomes and increases genetic diversity.

Front

What are sister chromatids?

Back

Identical copies of a chromosome, connected by a centromere.

Front

What is the role of meiosis in evolution?

Back

It contributes to genetic diversity, which is essential for natural selection.

Front

What happens during crossing over in meiosis?

Back

Homologous chromosomes exchange genetic material, increasing genetic variation.
