Very Bizarre 
The Mackenzie report alleges that Neville could be the biological father of the Twins
Please share your thoughts
Jeremy's defenders have long made allegations without any basis for them. This is one of them. The suggestion that because they share the same blood type as Nevill this means they most likely are Nevill's children is bizarre.
It is one of the things that demonstrates those writing the report have no idea what they are talking about and are hardly reliable. The various allegations in the they made in this document ended up going nowhere for the most part they were debunked by the time of the 2002 Appeal. This was supposed to be an internal document for the defense to try using as a basis to investigate further.
Frankly reading things like that just makes them look like fools who know little about science. Blood parental tests stopped being used because they could only rule out 30-35% of the population as being a parent so were of limited use.
When I was in 7th grade I learned the following in science class:
Mother has group A blood. Child has Group O blood. What blood type must the father have? The answer is A, B or O only AB is ruled out as being a possible blood type for the father.
So the father could have A, B or O blood. How much do you want to wager that Colin has one of these blood types...
For court orders of child support etc where parentage needed to be established they used immunity system tests to calculate parentage (HLA gene testing). These tests were somewhere in the 80 percent level so vastly superior to blood group testing. Naturally those who wrote the report had no access to such information to make any comparisons, they only had access to blood typing information and thus could only make the simplistic observation that my 7th grade class was taught- the father had to have Group O, A or B blood. That Nevill had group O blood is hardly a basis to suggest they were his kids instead of Caffell's kids.
