Single gene defect or mutation - Embryology

If the changes in a genome are restricted to a single gene, a single- gene defect ensues. Usually this involves a point mutation and leads to an altered amino acid sequence in the proteins that are coded in this section of the DNA.

Single-nucleotide polymorphism - Wikipedia A single-nucleotide polymorphism, often abbreviated to SNP ( s n ɪ p ; plural s n ɪ p s ), is a variation in a single nucleotide that occurs at a specific position in the genome, where each variation is present to some appreciable degree within a population (e.g. > 1%).

Mutation - Wikipedia For example, a butterfly may produce offspring with new mutations. The majority of these mutations will have no effect; but one might change the color of one of the butterfly's offspring, making it harder (or easier) for predators to see.
