WebMutations can cause a permanent change in the DNA of an organism. In the 19th century, Gregor Mendel determined rules to explain genetic inheritance using pea plants. WebMutations result in different forms of the same gene. These different forms are called alleles. For example, eye color is coded by different alleles of the same gene. When the DNA's instructions are read by the cell's machinery, these differing alleles can cause variations in the traits of organisms.
