Notice the population of beetles. The allele for color is seen on their backs: green (g) and brown (G) alleles. Green beetles are homozygous, gg. Brown beetles are heterozygous Gg in this population sample. The beetles' habitat is an old growth forest, where they burrow into the trees' bark for food and shelter. The coloration of the beetles help them to hide from predators, such as birds.

Since the leaf litter and small trees burned, we would expect a decline in the brown beetle population.

The wildfires destroyed all food sources for the beetles; we would expect to see a decline in both green and brown beetles.

Due to the wildfires, the entire beetle population would decline because they would not longer be camouflaged from predators.

The leaves will be destroyed and the green beetle population would decline because they would no longer be camouflaged from predators.

The brown beetle population would also be expected to decline since their food source and habitat were destroyed in the wildfires.
