It is important because when you compare the two, it gives the opportunity to know the reasoning behind factors that cause certain traits. In addition, wild-type mutants are used as a control in genetic research experiments.
Explanation:
Wild type shows phenotype characteristic of all members in the population where mutant show variation among the same population.
The importance of studying wild type and mutant individuals in genetics gives us a facility to study difference in phenotypic expressions and difference in genotypes in fruit flies.
It also helps us to study the mutation or variation in individuals and the reasons behind them.
