Which of the following is a difference between phase I and phase ll of meiosis? (1 point)

Question

• Anaphase, metaphase, and telophase only occurs during phase I of meiosis.
Phase I results in daughter cells with 23 chromosomes each and phase ll with 46 chromosomes each.
• Phase I results in two haploid daughter cells and phase Il results in four haploid daughter cells.
• Genetic variations can only occur during phase Il of meiosis.

Answer 1

The correct difference between phase I and phase II of meiosis is:

• Phase I results in two haploid daughter cells and phase II results in four haploid daughter cells.

In meiosis, phase I (meiosis I) is where homologous chromosomes are separated, resulting in two haploid cells. In phase II (meiosis II), each of those haploid cells divides again, resulting in a total of four haploid daughter cells.

The other statements contain inaccuracies:

• Anaphase, metaphase, and telophase occur in both meiosis I and meiosis II.
• Both phases result in haploid cells; phase I does not result in daughter cells with 46 chromosomes.
• Genetic variation due to crossing over can occur during phase I, and recombination during meiosis II doesn't introduce genetic variation.
