Question

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

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

Anaphase, metaphase, and telophase only occurs during phase I of meiosis.
Anaphase, metaphase, and telophase only occurs during phase I of meiosis.

Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.
Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.

Genetic variations can only occur during phase II of meiosis.

Answer 1

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

Explanation: Meiosis I is the reductional division (homologous chromosomes separate), producing two haploid cells. Meiosis II is an equational division (sister chromatids separate) and, after both rounds, produces four haploid daughter cells. Other statements are incorrect (both divisions have prophase/metaphase/anaphase/telophase; chromosome number does not go from 23 to 46; genetic variation mainly arises in meiosis I via crossing over and independent assortment).
