Question

some characteristics of a population increase the rate of evolution, whereas others decrease the rate of evolution. these trends can be represented by graphing the magnitude of the characteristic with the rate of evolution. place each characteristic with the graph that best represents the expected correlation.

Explanation:

• Population size: Larger population sizes generally increase the rate of evolution due to more genetic variation available, so it goes with the graph where rate of evolution increases with the characteristic (positive - slope graph).
• Strength of selective pressure: Stronger selective pressures speed up evolution, so it also goes with the positive - slope graph.
• Generation time: Shorter generation times mean more generations in a given time period, increasing the rate of evolution, so it goes with the positive - slope graph.
• Reproductive rate: Higher reproductive rates lead to more offspring and more genetic variation, increasing the rate of evolution, so it goes with the positive - slope graph.
• Genetic diversity: Higher genetic diversity provides more raw material for evolution, increasing the rate of evolution, so it goes with the positive - slope graph.

Answer:

• Population size: Positive - slope graph
• Strength of selective pressure: Positive - slope graph
• Generation time: Positive - slope graph
• Reproductive rate: Positive - slope graph
• Genetic diversity: Positive - slope graph
