The figure shows how natural selection of a single-trait gene affects lizard survival. Diagram of the effect of color mutations on lizard survival Which of the following most likely causes the changes in allele distribution? A. The allele for light gray coloration disappears from the population. This may be because light gray lizards are more visible to predators and therefore they might be less likely to survive and reproduce.
B. The allele for black coloration decreases fitness and becomes less common. This may be because black coloration keeps the lizards cool during hot summer temperatures.
C. Medium gray coloration in lizards appears to be a neutral mutant allele that allows the lizards to hide better from predators. This leads to increases in phenotypes and allele frequency of brown coloration.
D. Because black and medium gray lizards are less visible to predators, these alleles are neutral to natural selection and therefore will not disappear from the population of lizards.
