1: There are four stages of meiosis including prophase, metaphase, anaphase, and telophase. In the prophase phase (first stage) the chromosomes becomes visible as paired chromatids. When this happens the nuclear envelope disappears. During metaphase (second stage) the chromosomes attach to the spindle fibers. Throughout anaphase (third phase) the chromosomes move to opposite sides of the spindle fibers. While in telophase (fourth stage) two nuclei form by chromosomes and chromatids moving to the opposite ends of the cell.

2: The cells that outcome from meiosis are haploid daughter cells.

3: Haploid.

4: The similarities of meiosis and mitosis are that they both outcome with daughter from a parent cell. Differences are that mitosis has one round of genetic separation and cellular division while meiosis has two. In meiosis it creates daughter cells that aren’t identical.

Sexual reproduction combines genetics from two parents while asexual reproduction have offspring exactly the same as the genetics of the parent.

Asexual reproduction has the advantage of quicker reproducing. Sexual reproduction have all different offspring that can adapt to many different environments.
