i love red hair, what about you?
Red as in dyed red, or ginger?
 Red hair (or ginger hair) occurs naturally in 1–2% of the human entity
Yeah it is quite uncommon, and unfortunately they have developed quite a bad reputation! Did you hear about what happened in Denmark?
No. Red hair  occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations.
They were rejecting sperm donors who were ginger! Quite ridiculous. Both my brother and mother are ginger.
really?  Red hair appears most commonly in people with two copies of a recessive allele on chromosome 16
I find all the genetics rather difficult to understand! What does that actually mean?
it produces an altered version of the MC1R protein.
What makes it so rare then? Why isn't it more common?
