Which mode of natural selection is demonstrated by the Ginkgo tree today remaining essentially similar morphology since the Mesozoic era? a. stabilizing b. directional c. diversifying d. sexual e. artificial 17. Which scenario will demonstrate disruptive (diversifying) selection? a. There is heterozygote advantage (heterozygous individuals have the highest fitness). b. Female flies collect sperm from different males in her sperm bag. c. Individuals with intermediate phenotype are inferior competitors against homozygous individuals d. Insects become resistant to the most...
In the case of directional selection, if the advantageous allele (b) is recessive and a less advantageous allele (B) is dominant: A. b will be lost in the population because the dominant allele will increase in frequency by natural selection B. b will increase in frequency at the same speed as if it was a dominant advantageous allele, because what matters is the coefficient of selection and not if the allele is dominant or recessive C. b will increase in...
