SNPs are single-nucleotide polymorphisms, or variations in a single base pair of DNA. While there are millions of SNPs in the human genome, only a small percentage are likely to actually impact our characteristics or traits (phenotypes). Studies have estimated that this percentage is likely less than 1%, so choice B, "<1," is the best answer.
