Indicate true (T) and false (F) statements below regarding human genetic variations. Your answer would be a four-letter string composed of letters T and F only, e.g. TFTF. ( ) The genomes of two randomly chosen humans are expected to be identical with respect to at least 99.99% of the nucleotides. ( ) Copy number variations can contain genes. ( ) If the frequency of a point mutation in a population is only 0.1%, with no mutation at this site in the rest of the population, then the variation is NOT considered to constitute a single-nucleotide polymorphism. ( ) Most of the common genetic variants in the current human population could have been present in a human ancestral population of only about 10,000 individuals.
