Genetics/red hair in my beard?

Advertisement


Question
To start off, I'm 18 and have recently started growing my beard out fully. I have noticed that I have a large amount of red hair intermingled with my dark brown (almost black hair). I have red hair all along my chin and jaw line. My dad has a full beard also but no red hair but my brother has a few red hairs also. As far as I know I have no red headed family remembers. So what could it be? 

Answer
Hi Alex,

If you are a Caucasian, then there is a good chance that some ancestral genes that came together, one each from your parent to give a red color beard.
Unless something is known of your ancestry, it is difficult to say. The other possibility is that there has been a de novo mutation in the germ cells of parents, giving rise to red color.
Or, finally, an exposure to some external agents could have caused it.
