The nucleotide sequences between individuals differ by 0.1%, yet the human genome is made up of about 3 × 10⁹ nucleotide pairs.Which of the following statements is FALSE?

Question

Quizplus · Accepted Answer

Option A is a true statement, as homologous autosomes differ from each other by 0.1% in most human cells. Option B is false because not all changes between human individuals are single-nucleotide polymorphisms (SNPs). There are also other types of genetic variations like insertions, deletions, inversions, and duplications that contribute to genetic diversity. Option C is true as two individuals (other than identical twins) will generally have more than 3 million genetic differences in their genomes. Option D is also true as much of the variation between human individuals was present 200,000 years ago when the human population was small.
