!. Describe in detail how insertion,deletion, and base substitution of nucleotides can have asignificant impact on genes. Find three specific examples (actualgene mutations, not chromosome mutations) of ways in which avery small change in DNA can have a major impact on an organism,and describe each mutation in detail.
2. Why do agricultural researchers intentionally producepolyploid crop plants? Explain in detail what polyploidy means anddiscuss different types of polyploid plants. Give four specific detailed examples ofactual commercial crops that are polyploid. In each case explainwhy polyploidy is advantageous. Also, indicate whether thepolyploidy occurred naturally or describe how botanists created thenew varieties. Why is it more common for polyploidy to occur inplants than in animals? Give examples of types of animals that havebeen found to exhibit polyploidy.
