Back

To produce gametes with half the number of chromosomes.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes (2n), while haploid cells have one set (n).

Front

What is crossing over and during which process does it occur?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during meiosis.

Front

What are sister chromatids?

Back

Sister chromatids are identical copies of a chromosome connected by a centromere.
