Question

Gene mutations can be beneficial, detrimental or neutral

Beneficial mutations change the gene sequence (missense mutations) to create new variations of a trait

Detrimental mutations truncate the gene sequence (nonsense mutations) to abrogate the normal function of a trait

Neutral mutations have no effect on the functioning of the specific feature (silent mutations)

Accepted Answer

New alleles are formed by mutation.
