Urgent!!!!! How can a mutation benefit an organism and its descendants? Provide an example.
Mashcka [7]
A mutation can allow a organism to adapt to the environment and example can be the case of the peppered moth which has two variations a white colored one and a black colored one. The white colored ones were able to survive better that the darker ones because of how they were able to camouflage with the lichen located in the trees.
