[Haskell-cafe] Implementing parental using blood type

To solve the specific problem you pose, one doesn't need to know anything
about the relationship between alleles and blood types -- you don't even
need to know what an allele is :-)

If I didn't need to do anything else than just calculate whether a given
father's blood type is 'viable', I'd rather go for something like the
solution in attachment. I took advantage of this handy calculator
<http://www.endmemo.com/medical/bloodtype.php> while writing it.
