Common gene variants for skin tone found – LIFE

All the nine SNPs that are significantly associated with skin pigmentation are found in chromosome 15.

The researchers found a few SNPs are found close together as two blocks in the chromosome. While one block of the chromosome has two SNPs, the other block has three SNPs. SNPs found together tend to have combined effect on skin colour. Since children tend to inherit small blocks of chromosome from parents, the SNPs found close together are inherited as a whole from parents.
