We discussed blood types in General Biology today as an example of a trait where there are more than two alleles present in the population – the three most common of these alleles are the A allele (IA, IB and i). Last semester I wrote an essay here discussing this trait and how it is truly expressed (rather than the more simplified terms I used in class) and I wanted to point anyone interested in reading more about that here.
dYou can also find a cute game about blood typing and transfusions at NobelPrize.org. The game emphasizes the importance of blood typing prior to transfusion and discusses which blood types are able to be transfused into what patients. Again, it’s cute and simple, but makes a good point.
