Subject: Re: [DNA] Sykes' data shows E3b absent entirely from "CentralEngland"

I see 37 labeled E3b haplotypes in Capelli's British Isles. That seems
about 2 percent.

193 haplotypes from "Central England" would then have expected value of
about 4 E3b if average. But standard deviation of 4 haplotypes is plus or
minus 2 haplotypes; 1/3 the time you should expect 0 or 1 or greater than 6
to be the outcome if 4 was the expected or most likely.

You are skirting on the edge of statistical significance. Another
explanation might be that E3b came via maritime commerce circumstances, so
interior England would be lighter than average on their presence.

What is interesting is the complete absence of E3b in this region, according
to the Sykes survey data of 193 haplotypes in Central England. The region
is surrounded by "North England," "East Anglia," "London," "South England,"
and "Wales" (the data set does not distinguish between South Wales,
Mid-Wales and North Wales). Within these regions, E3b appears at a
frequency of 2-5%. Capelli showed similar percentages in specific locations
surrounding this area, from 3-6% of the population, although he managed to
overlook the Sykes "Central England" area entirely.
