Question

Quizplus · Accepted Answer

Single nucleotide polymorphisms (SNPs) are variations in a single nucleotide of DNA that can occur in a population. As per studies, SNPs occur on average once every 1,000 nucleotides. Since the human genome comprises roughly 3 billion nucleotides, this means that each human differs from every other human, on average, by 0.1% (3 million / 3 billion) of the human genome.
