text: Mutations in genes can either have no effect, alter the product of a gene, or prevent the gene from functioning properly or completely.
text: However, given that many mutations have effects too small to be detected and that mutagenesis experiments can detect only mutations of moderately large effect; DNA sequence data analysis can provide valuable information about these mutations.
text: Mutations within introns and in regions with no known biological function (e.g. pseudogenes, retrotransposons) are generally neutral, having no effect on phenotype - though intron mutations could alter the protein product if they affect mRNA splicing.
text: Most mutations either have no effect, are deleterious, or are lethal; some provide survival benefits, which are passed on to progeny.
