Question
The Vietnamese mossy frog blends in with its environment, so it is less preyed on by snakes.Determine the most likely effect of this selection pressure over many generations.*1 pointAn increase in the number of genetic mutations.An increase in the variation in skin colour in the population.An increase in the frequency of the green colour trait.An increase in the frequency of the red colour trait.
Solution
The most likely effect of this selection pressure over many generations would be an increase in the frequency of the green colour trait.
Here's why:
-
The Vietnamese mossy frog uses its green color as a form of camouflage to blend in with its mossy environment. This helps it to avoid being detected and eaten by predators such as snakes.
-
Over many generations, those frogs that are better able to blend in with their environment (i.e., those with a green color) are more likely to survive and reproduce. This is known as natural selection.
-
As these green frogs reproduce, they pass on their green color trait to their offspring.
-
Over time, this leads to an increase in the frequency of the green color trait in the population, as those with the trait have a survival advantage and are more likely to pass on their genes to the next generation.
-
Therefore, the selection pressure exerted by the snakes preying on the frogs would most likely lead to an increase in the frequency of the green color trait in the frog population.

Read each of the scenarios below. Then, select the option that best represents a scenario illustrating natural selection.A In a population of birds, those with larger beak sizes are better able to crack open tough seeds, providing them with a food source during periods of scarcity. Consequently, the average beak size in the population decreases.B In a population of flowers, those with a particular color variation attract more pollinators and produce more offspring. As a result, the proportion of flowers with that color variation decreases over generations.C In a population of rabbits, those with longer legs are more successful at outrunning predators and are more likely to survive and reproduce. Over time, the average leg length in the population increases.D In a population of fish, those with brighter colors are more easily spotted by predators, leading to higher mortality rates. As a result, the proportion of fish with bright colors increases over time.
