Redheads
You have probably seen a red head in
your lifetime, if not then go to Ireland or Scotland.
There is of course scientific
reasoning as to why redheads are well redheaded, but you may not know what they
can do.
Red heads actually get their hair
colour the same way we all get our hair colour, Melanin.
We all have melanin
it is associated with the Melanocortin 1 receptor (the simpler way of saying it
is the MC1R gene.) Redheads actually have a mutated version of it. This gene is
used for making protein receptors found on the melanocytes, they produce
melanin, which makes our skin, and eyes be different colours.
This gene is recessive, which means
that if two parents have the recessive gene they are able to have a ginger
child even if they do not have ginger hair. So they are not going extinct to
much debate. Sorry…
Red heads are very
common in the UK, which is accustomed to the lack of sunlight. With the lack of
sunlight there, their pale complexion absorbs Vitamin D much easier than people
who have darker skin.
Redheads actually
need 20% higher dose of anaesthetic compared to a non-red head. But they are
more sensitive to thermal changes and pain. There are still queries as to why
this is true, but scientists presume that it is because our MC1R gene is linked
to endorphins (natural pain killers.)
