This is because most founder mutations are recessive this means you would have to have two copies of the gene (one from both parents) to be affected by the mutation a person with only one copy of the gene is called a carrier. A gene is a long sequence of nucleotides on a dna molecule a mutation is a change in the amount of an organism’s genetic material and when a change in genotype produces a change in phenotype, the individual affected is said to be a mutant.
Frameshift mutation: this mutation is the result of an insertion or a deletion of one or more nucleotides from the dna sequence but not in multiples of three because bases in set of three forms a codon which provides the code for an amino acid sequence of the protein.

Most of the forms of mutation we discuss in this essay appear suddenly (ie, in a single generation) and affect just a few generations yet even such seemingly normal characteristics as our ten fingers and ten toes or our two eyes or our relatively hairless skin (compared with that of apes) are ultimately the product of mutations that took shape over the many hundreds of millions of years.

Biology: mutation and article essay that errors can occur, as well as mutations examples of errors that occur are single-gene mutations these types of mutations can be classified as point mutations, which result in a change in a single base pair within dna.
In biology, term- mutation has been described as changes to the base pair sequence of the genetic material of an organism mutations can be caused by: copying errors in the genetic material during cell division, by exposure to ultraviolet or ionizing radiation, chemical mutagens, or viruses, or can occur deliberately under cellular control during processes such as hypermutation. Processes that increase the rate of changes in dna are called mutagenic these chemicals promote errors in dna replication, often by interferring with the structure of base pairing while u v radiation induces mutations by causing damage to dna structure.
