Document Summary
Lecture potential exam questions: compare artificial selection with natural selection. Artificial selection is the process of human-directed selective breeding aimed at producing a desired set of traits in the selected species. Humans have been selectively breeding grains such as barley and wheat, as well as lentils and peas for more than 10 000 years. Crops that are the hardiest, quickest growing, and best tasting are chosen as the parental stock for the next generation (i. e. Strawberries that are brighter in colour, larger in size, and sweeter in taste). If this process is repeated over time, the population of plants increasingly takes on these beneficial characteristics. Natural selection is the evolutionary process by which beneficial alleles increase in frequency over time in a population because of increased survival and reproductive success of individuals carrying those alleles. It is the consequence of variation, inheritance, and differential survival.
