There is a small population of beetles on grass in which some are green and some are brown in color. A group of students is passing from that place and walks on them. By chance, green color beetles are pressed under their feet resulting in:
Correct answer: C. Change in the genetic equilibrium of that population
- A. The balance of the genetic equilibrium of that population
- B. No effect to the genetic equilibrium of that population
- C. Change in the genetic equilibrium of that population
- D. Genetic equilibrium doesn't apply in that population
Explanation
The genetic equilibrium of the population will be affected because green beetles can camouflage with green grass and as a result can be pressed under the feet more often than brown beetles. This will disbalance the ratio of the brown allele to green allele, as the number of green alleles will decrease.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
