WebApr 11, 2024 · A frameshift mutation in a gene refers to the insertion or deletion of nucleotide bases in numbers that are not multiples of three. This is important because a cell reads a gene’s code in groups of three bases … WebThe small differences in DNA base sequences between individual organisms within a species population is called genetic variation. Genetic variation is transferred from one generation to the next and it generates phenotypic variation within a species population. The primary source of genetic variation is mutation (changes in the DNA base ...
