Answer:

1. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. In meiosis II, these chromosomes are further separated into sister chromatids. Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.

2. Answer! A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer. I hope it helps! :)
