To make my question understandable giving an example will make it easier for me to ask.
DF13 is a recently discovered SNP under L21.
If a line of males , all of whom are L21+ DF 13 + , live in area long enough can they produce a person who loses the DF13+ to become DF13-.
Up to now I have assumed that the SNP DF13+ would spontaneously appear in the L21 group. Leaving behind the L21’s who did not mutate.
However as I gave this some thought it occurred to me that perhaps all the L21’s where DF13+ and a mutation occurred where this SNP was lost.
Does this question make sense and is this possible? Can mutation of a SNP work either way?
