Question

Quizplus · Accepted Answer

A variant in DNA sequence that is present in at least 1% of a population is called a polymorphism. This means that it is a common genetic variation that occurs in the DNA sequence among individuals. Micromutations and macromutations refer to smaller or larger genetic changes, respectively. An allele is a variant form of a gene and a genome refers to the entire set of genetic material present in an organism. Therefore, the best choice in this case is A) polymorphism.
