1. Why is the chromosome number reduced by half through meiosis? How is genetic diversity achieved during the meiosis process?
2. Many species can reproduce either asexually or sexually. Contrast asexual and sexual reproduction processes, analyze the advantages and disadvantages of both. Predict which reproduction will be favored when the organisms face unfavorable environmental conditions. Why?
