Question

Quizplus · Accepted Answer

Mutations are random changes in DNA that can occur spontaneously or through external influences, such as radiation or chemicals. When mutations occur in sex cells, they can be inherited by offspring. Mutations can sometimes have a positive or negative effect on an organism's fitness, but they are generally considered random in terms of their impact on an organism's reproductive success. Therefore, the statement that best describes the concept of mutation is that it is inheritable when occurring in sex cells and is random in terms of fitness of organisms.
