A research team is studying a population of snails to determine how quickly characteristic B will pass from one generation to the next. At the start of the study, 20% of the snails have characteristic B. After five generations, 81% of the population has characteristic B. Find
the percent of the population that will have characteristic B after eight generations. (Assume a = 2 and b = 1. Round your answer to the nearest whole number.)

Which of the following would result in this population neith growing nor shrinking?arrow_forwardWhich of the following statements about the "greenbeard" effect is correct? Richard Dawkins first hypothesized the existence of the "greenbeard" allele to explain why we observe some unusual phenotypes, such as green beard. According to the hypothesis, the reason why the greenbeard phenotype is selected for is because the greenbeard individuals would preferentially receive altruistic benefit from non-greenbeard individuals. The reason why the "greenbeard" hypothesis is possible is because when direct fitness and indirect fitness are in conflict, it is always the factors that increase the direct fitness that will triumph over the factors increasing the indirect fitness. The "greenbeard" effect shows that it is possible to evolve altruistic behavior toward individuals who are not genetic kin.arrow_forward

(see figure above) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations. This data does not help us understand effects of gene flow on fitness. The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population. The gene flow between hatchery-reared and wild populations is increasing the fitness of the wild populations.arrow_forwardThe following table depicts characteristics of five prokaryotic species (1-5).

- Small birds like that in (Figure 1) can migrate over long distances without feeding, storing energy mostly as fat rather than carbohydrate. Fat is a good form of energy storage because it provides the most energy per unit mass: 1.00 grams of fat provides about 9.40 (food) Calories, compared to 4.20 (food) Calories per 1.00 grams of carbohydrate. Remember that Calories associated with food, which are always capitalized, are not exactly the same as calories used in physics or chemistry, even though they have the same name. More specifically, one food Calorie is equal to 1000 calories of mechanical work or 4184 joules. Therefore, in this problem use the conversion factor 1 Cal = 4184 J. Figure 1 of 1 Part A Consider a bird that flies at an average speed of 10.7 m/s and releases energy from its body fat reserves at an average rate of 3.70 W (this rate represents the power consumption of the bird).
