Why some of us have red hair (https://i.pinimg.com/originals/4b/42/0d/4b420d929c8fdb1fcecfb32539d2d440.png)? This seems to be caused by some mutations like C->T (https://www.snpedia.com/index.php/Rs1805007) in the rs1805007 snp of the MC1R (https://en.wikipedia.org/wiki/Melanocortin_1_receptor), a gene in the 16th chromosome and some others like C->G in Asp294His/rs1805009 (https://www.snpedia.com/index.php/Rs1805009). When persons have only one copy of the allele in one chromosome they get only some red hair and when they have two copies in both chromosomes they are fully redhaired.
But where and which populations has this mutation originated from? Is there only one type of red hair or are there different types?
Was it inherited from Neanderthals or was it spread by R1b or mtdna I, or it has a different source? The y-dna K group seems to have been blond as a whole, so it would seem odd that only R1b has this trait.
