What best describes genetic mutations?
1 Answer
A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms.
Explanation:
mutations are accidents in the copying of DNA. Somatic mutations are accidents that occur in the bodies cells. These mutations often result in cancer, or a deformed limb or other body part. These mutations are not passed on to other organisms or except those directly affected.
Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo. These changes if they are in the germ cell will be passed on to other organisms formed by sexual reproduction or asexual reproduction. An example would be the golden delicious apple. A lost of genetic information due to a mutation resulted in a different color of fruit.
The accidental changes in the DNA can be a point change like in the disease of Cycle cell amenia. It can be the reproduction of extra chromosomes like in Down's syndrome. It can be the shift of the DNA code sequences due to the loss of a nuclide pair. ( Usually fatal)
A genetic mutation are unfortunate accidents that affect the entire organism and can be passed on to further generations of organisms.
