- What is a recombianation event?arrow_forwardWe considered the sympatric evolution of reproductive isolating mechanisms in host races of Rhagoletis pomonella, the apple maggot fly. The wasp Diachasma alloeum parasitizes apple maggot flies, laying its eggs on the larvae of the flies. Immature wasps hatch from the eggs and feed on the fly larvae. Research by Andrew Forbes and his colleagues (Forbes et al. 2009. Science 323:776–779) demonstrated that wasps that parasitize the apple race of R. pomonella are genetically differentiated from those that parasitize the hawthorn race. They also found that wasps that prey on the apple race of the flies are attracted to odors from apples, whereas wasps that prey on the hawthorn race are attracted to odors from hawthorn fruits. Propose an explanation for how genetic differences might have evolved between the wasps that parasitize the two host races of R. pomonella. How might these differences lead to speciation in the wasps?arrow_forwardWhat are some other prezygotic reproductive barriers besides a mating dance?arrow_forward
- The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? * nd 2 school The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1.492 finches is introduced to a rainforest.
