A population of beetles lives on a forest floor, which is covered in dark leaf litter. Dark beetles have the genotype A2A2, while lighter beetles have an A1A1 genotype; heterozygotes have a phenotype that is closer to that of the A1A1 homozygotes. The oppresso bird preys on these beetles. What do you predict will be the outcome of this predation over time?
A) The colour of each beetle within the population will gradually change over time.
B) Beetles will have darker-shelled offspring to protect them from predation.
C) The proportions of beetles having different traits within a population change over time. The proportions of beetles having different traits within a population change over time.
D) Behaviours learned from the beetles will be passed onto their offspring.
E) A mutation will arise that will result in a darker shell colour and protect the beetles from predation.
