A population of lizards lives in an isolated area where local rocks contain a high concentration of radioactive elements. A study of this population would MOST LIKELY show A) a lower than average mutation rate. B) a higher than average mutation rate. C) a higher survival rate than other lizard populations. D) an increase in size compared to other lizard populations.
We know that animal populations exposed to higher concentrations of radioactive activity, often suffer deleterious genetic mutations. Thus, the answer would be B.) a higher than average mutation rate.
