Question

During which part of meiosis (meiosis I or meiosis II) do the two alleles of a gene separate? During which phase does the separation occur? State your answer as meiosis I or meiosis II followed by a comma and the name of the phase (for example, if your answer is meiosis II and metaphase, enter meiosis II, metaphase).

Answer 1

Answer:

The answer is meiosis II, anaphase

Explanation:

During meiosis I, cells are duplicated. Thus, the number of alleles of the two daughter cells are as same as the original one.

In meiosis II, the two daughter cells are divided into 4 gametes.

• Prophase II, there is not any cell duplication. The number of alleles are not changed.
• Metaphase II, chromatids containing genes are lined up in the middle of cell, then spindles attach to each of sister chromatids.
• Anaphase II, these chromatids are separated, leading to two alleles of any gene separate.
• Telophase II and cytokinesis, cell membranes are formed.
