I refer you to my posts 3953 and 3968. Based upon authority I would calculate that the mtDNA said to relate to Kosminski could, in fact, have belonged to any one of about 95000 Londoners, living in 1888, out of a population of 5,476,447: http://www.jack-the-ripper.org/metro...olice-1888.htm
This represents 1.736% of the population of London at the time, i.e. the estimated percentage of Londoner's that would have shared Kosminski's mtDNA: see posts 3753, 3968.
However, we do not know that the genetic material was deposited in 1888 or by a Londoner so the actual odds are probably far greater than 1 in 95000.
Of course, these odds could be shortened if we had other evidence linking Kosminski to Eddowes- such as reliable testimony from an eye witness who saw them together shortly before the murder!
It would also help if we could establish that the genetic material was deposited on the shawl sometime in the 19th C and in London!
However, as things stand it seems that the DNA evidence relating to Sickert, provided by Patricia Cornwall, gives us a more reliable match!
And, unlike Dr Jari, I am, of course, willing to submit my conclusions to this Board for peer group review!
Best wishes,
John
