Genetic variation among humans is relatively small when compared to other species.Where in the human genome does most of the diversity occur?
A)in sequences that code for tRNA
B)in the homeotic genes
C)in single nucleotide-polymorphisms
D)in the mitochondrial DNA

Question

Genetic variation in humans primarily occurs in the form of single nucleotide polymorphisms (SNPs), which are single base pair differences in DNA sequences. While there are also variations in mitochondrial DNA, they account for a smaller proportion of overall human genetic diversity. Variations in genes that code for tRNA or homeotic genes are unlikely to account for most of the genetic variation in humans.
