Use the following information to answer the next question. The caterpillar of the diamondback moth is controlled by treating it with an insecticide called Bt. A caterpillar population in an area treated with Bt is becoming resistant to Bt. You are given 10 male diamondback moths and 10 unfertilized female diamondback moths from an area that has never been treated with Bt insecticide and another group of 10 male diamondback moths and 10 unfertilized female diamondback moths from a population that has developed resistance to Bt. Long Answer – 15% 1. a. Describe an experiment that you could carry out to determine whether or not the resistance is due to a recessive allele (a) or a dominant allele (A). Describe the results you would expect if the resistance trait is recessive and the results you would expect if the resistance trait is dominant. Use diagrams, tables, or Punnett squares to clarify your answer. ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... ....................................................................................................................................................... 26
