1 -- what is haplogroup frequencies regarding of haplogroups case ?

2-- haplogroup frequencies is high mean what? or low mean what?

i saw article that haplogroup-- R1b --(y-chromosome)frequency is high in Europeans (west-one) and low in turkey.
and low in many other --Arab countries --also their some percentage of population (say 9-15%)also
hold --R1b-- haplogroup

SO, DOES THIS MEAN DESPITE HOLDING SAME HAPLOGROUP THEY ARE NOT BELONGS TO --R1b--HAPLOGROUP BECAUSE THEY HOLD LOW FREQUENCIES OF SAME HAPLOGROUP(R1B)

I KNOW -( Y-CHROMOSOME ) GOES FATHER TO SON GENERATION TO GENERATION
DIRECT LINE BUT WHY LOW AND HIGH FREQUENCIES ---THAT"S MY PROBLEM


PLS EXPLAIN WITH SIMPLE WAY

THANKS IN ADVANCE
