How are new alleles created? Occasionally, DNA mutations occur in germ cells – cells destined to become eggs or sperm. In this case, the DNA mutation is copied into every new cell of the growing embryo following fertilisation. ... If the mutation affects a gene, it will result in a new version of that gene – a new allele.
