Question

Gene mutations can occur in somatic or germ cells and have varying impacts on the organism. Do you feel that all genetic mutations should be considered adverse or is it possible for genetic mutations to have positive impacts?

Answer 1

Although genetic mutations have many adverse effect and genetic mutation may lead to various kinds of genetic diseases, genetic mutation has a great positive impact in evolution of organisms.

Genetic mutation causes many diseases like cystic fibrosis, sickele cell anemia, Tay-Sachs disease, phenylketonuria color-blindness etc.

Genetic mutation accumulation over a long period may lead to may advantageous outcomes which is known as evolution. For example, genetic mutation due to environmental stress condition may develop a trait in animal which may be an adaption towards stressed condition in organisms.
