Explain how bacteria reproduce. Which factor do they rely on to increase genetic variation? Discuss the advantage(s) and disadvantage(s) of asexual reproduction in the light of evolution.
Explain how meiosis and sexual reproduction generate biodiversity. Discuss the advantage(s) and disadvantage(s) of sexual reproduction in the light of evolution.
Loss of biodiversity or “genetic erosion” is a problem affecting plants and animals, but not only in the wild. The Food and Agriculture Organization (FAO) of the United Nations estimates that “17% of the livestock breeds reported in the course of 2013¬–14 to FAO by countries are classified as at risk of extinction.” How can you explain the genetic erosion observed in agriculture? Do you think that humans are responsible? Provide solutions that could reverse that problem and discuss the consequence(s) if no actions are taken. Do you think that we could be affected in our everyday life? Explain.
