Question

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.

Answer 1

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.
