Genetic diversity can increase the chance of the flies population to be better adapted or resistant to the pollution. See explanation below
Explanation:
Genetic diversity refers to variation among the genes contained in a particular species of organisms. Genetic diversity occurs during production of gametes (meiosis) in sexual reproductive organisms. According to the question, a forest is home to a population of flies with high genetic diversity.
Genetic diversity will help the fly population survive an exposure to pollution from a factory by increasing their adaptation to the pollution. It is very likely that some of the fly population will contain allelic variation that will help them resist the effect of the pollution in the forest. The surviving flies will produce offsprings that will carry the set of resistant genes.
It is better to compare the average height gain of control and experimental groups of plants to eliminate all other variables.
Explanation:
If you evaluate individual plants, the data may vary. The experimental group is the one where an experimental procedure is performed while the control group does not receive any treatment.
