SNP

(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）ゲノム内の単一のヌクレオチドが変化したときに生じるDNA配列の遺伝的変異；一塩基多型は通常、種の一連の集団において有意な割合で繰り返し生じるほど進化的に成功した点突然変異とみなされる
