Based on knowledge of mitosis and meiosis, explain the significance of the change from reproducing asexually to sexually due to a change in environment.
Many species can reproduce either asexually or sexually. In a favorable, stable environment these organisms reproduce asexually. When the environment changes in some way that is not favorable to the organisms, they begin to reproduce sexually. Based on knowledge of mitosis and meiosis, explain the significance of this change.

Some organisms have developed this ability through evolution. Mitosis is used as a form of asexual reproduction because it used the exact same as the parent cell. Plants that undergo asexual reproduction, their offspring look exact same as the parents. Since asexual reproduction only require one parent, this would make sense that the offspring would be the exact copy of the single parent. Meiosis forms gametes that are used for sexual reproduction. Meiosis undergoes a process called "crossing over or recombination" that introduces genetic diversity. Animals that undergo sexual reproduction use two parents to form an offspring. Meiosis creates male (sperm) and female gametes (egg) that combined fertilization to form a zygote. The zygote then differentiates into a baby. If an animal or plant has the ability to switch between mitosis and meiosis, there must be two separate mechanisms for each. I am not aware of any species that have this capability.
