Explanation:
The answer is: It will depend whether this mutation will make those lizard more fit than the others.
Genotype variations that will increase the
chance of survival and reproduction of some organism are preserved and will be
inherited. <span>Fitness describes a reproductive success of an individual. For example, there are green lizards in a population. After a mutation, there are now some yellow lizards in population. If a color affects the reproductive success, for example, yellow lizards will have more offspring, and their allele will be inherited. So, the frequency of the new allele will increase.</span>

A human ear on average can tell the difference between sound waves at the range of 20Hz to about 20kHz (20,000 Hz). So the lower range will be at lesser than 20Hz.
