(genetics) genetic variation in a DNA sequence that occurs when a single nucleotide in a genome is altered; SNPs are usually considered to be point mutations that have been evolutionarily successful enough to recur in a significant proportion of the population of a species

(遺伝学) ゲノム内の単一ヌクレオチドが変異することで起こるDNA配列の遺伝的変異。SNPは、進化的に成功し、ある種の集団のかなりの割合で繰り返し現れるポイント変異とみなされる。
