Genetic Variation is Ultimately Based Upon Which of the Following

Question

Genetic variation is ultimately based upon which of the following?
A) Morphological differences
B) Small variations in nucleotide sequence of the DNA
C) Carbohydrate content of the cell
D) Translation

Accepted Answer

Genetic variation is based on variations in the DNA sequence, which can be caused by mutations or the shuffling of genetic material during sexual reproduction. Morphological differences and carbohydrate content of cells are not directly related to genetic variation, and translation is a process by which the genetic information in DNA is used to build proteins, not a source of genetic variation in itself.
