Answer:
A mutation can create a new allele of a gene by changing the DNA sequence of the gene. A gene is made up of a sequence of nucleotides, and a mutation can occur when one of these nucleotides is altered. For example, a single nucleotide change can result in a different amino acid being incorporated into the protein that is produced from the gene. This can affect the structure and function of the protein, which can lead to new traits in the organism that carries the mutated allele.
If the mutation occurs in a gamete (a sperm or egg cell), it can be passed on to the next generation. If the mutation provides a selective advantage to the organism, it may become more common in the population over time, leading to the creation of a new allele. Over many generations, accumulation of mutations can result in the evolution of new species with unique traits and characteristics. Therefore, mutations are a key driving force of genetic diversity and evolution in populations.
