Step 1
Fitness, in evolutionary biology, refers to reproductive success. A strategy that maximizes the number of offspring that survive to reproduce will be the most fit. Show more…

'Which of the following big sagebrush plants the most fit; based only on the information presented? The individual that produces 3% more offspring each year than others in its population The individual that produces 5% more distasteful chemicals, making it 2% ess likely to be attacked by herbivores than others in its population. The individual that can survive with 10% less water than the others population_ The individual that is the most resistant to disease organisms the population_ All of these individuals are equally fit based on the information presented'

Stephen Franks and colleagues found that populations of annual field mustard evolved to flower more quickly during a drought period, resulting in a higher probability that plants would reproduce before they died. Suppose a news story explained this result by stating "the mustard plants evolved earlier flowering in order to become better adapted to drought conditions." What, if anything, would be a better way to explain these results? A. Early-flowering mustard plants grew faster than late-flowering plants, and thus replaced them. B. Early-flowering mustard plants produced the most offspring during the drought, which inherited their genes for early flowering. C. The mustard plants evolved earlier flowering in anticipation of future drought conditions. D. The news item is already a good explanation of natural selection and doesn't need any correction.

A large sunflower population is established in a field. The flowers mate randomly, and all individuals are equally likely to survive and reproduce. In this population, 80% of the alleles of a gene for petal color are dominant and 20% of the alleles are recessive. Given this information, after many generations, which of the following options would be most likely?
