Classical Genetics Notes
... Most genes in a population exist in only two allelic forms. For example, pea plants can be either tall (T) or short (t). When there are more than two allelic forms of a gene, we refer to that situation as multiple alleles. In humans there are four different blood groups: A, B, AB, and 0 determined b ...

Point mutation
A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
