If one or more of these mutations occurs in the genes of reproductive cells, how might the traits of offspring be affected? a. they may be harmed. b. they may not be affected at all. c. they may receive a benefit

Usually when a mutation occurs it is for the better of the organism.

So I would say C.) they may receive a benefit.

Good Luck! :)
