1) determine the probability of individuals inheriting a disease
2) In the future, new genetic mutations will arise, and knowing to understand genetics would be important in helping analyze the problem/mutation in genetic recombination.
3) Genetics allows us to link diseases to one another (pedigrees) by analyzing if they are recessive, dominant, and/or autosomal, this allows us, as scientists to be able to identify and classify future diseases, and to determine their inheritance pattern, in the future.
