• In 1944 the actress Joan Barry (blood group A) sued Charlie Chaplin (blood group O) for support of her child (phenotype B).
• The blood group evidence was presented in court.
• The jury supported Joan Barry’s claim. Were they right?
The mother must be Heterozygous A (Ao)
The child must be Heterozygous B (Bo, inheriting the “o” from mother)
The child must have inherited a “B” from the father.
Charlie Chaplin was Homozygous O (oo) and therefore could not have been the father.
