If you just give a unit of blood to someone else, the chance is 50% it will be compatible.
This is related.....
If there were just two blood groups, M and N and one was 90% incident and the other 10%
then no matter who the parents are ! The chances are that boths sibs will be M and concordant....around 80%
I'll think about it....
Remember that A is not compatible with O, but A can receive O yet O cannot receive A.
The problem of working out if a population is AO or AA is not that difficult - Take the blood groups to be
0 - 44% A 42% B 12% AB 2% - it is around about that for Northern Europeans. Your 42% A is made up of AO and AA genotypes.
However O is OO and so if the genotype (p-squared) is 44 then the gene frequency is the square root of this (p) and I have taken this to be 2/3 - [0.67] . A per cent is less than one and squar roots of numbers less than one are greater than the number.The square root of 0.4 is around 0.6
We know can conclude in a mixed population that in your 42 % A one two thirds is AO and one third AA., to wit 28 and 14 - adding you will notice up to 42
der daaah
so now - after all you have to do something - make up a matrix 6 x 6 with O, AO,AA,BO,BB,AB along the top and down the side. In the box OO OO, this will occur 44% x 44% of the time, about 16% and all will be compatible so write 16%.
In the O AO box - I reckon 50% are gonna be compatible. and this pairing occurs 44% x 28% which I think is around about 10% so in this box, write 5% because only half are going to be compatible....
HA HA I will let you fill in the other 34 boxes !!
then you add up all the perdentages....
I still reckon is gonna be around 50%
Have a good week-end.
