In short, the answer is 25%.
Dave and Lisa both have genotypes of Bb. Using a Punnett square, you can calculate that their child has a 25% chance of having the genotype BB, 50% chance of having the genotype Bb, and 25% chance of having the genotype bb. Translate these to phenotypes, and their baby will have a 75% chance of having brown eyes and 25% chance of having blue eyes.

produced by the Industrial Revolution in the 1800s resulted in trees to darken

blend in against a similarly dark background. Natural selection or
microevolution favoured the darker moths, therefore their proportion within the
moth population increased.</span>
