    Multiple Alleles
    • Mendel implied that only two alleles, one dominant and one recessive, could exist for a given gene. We now know that this is an oversimplification. 
    • Although individual humans (and all diploid organisms) can only have two alleles for a given gene, multiple alleles may exist at the population level.
    • Therefore, many combinations of two alleles are observed.
    • The example of ABO blood grouping also provides a good example of multiple alleles.
    • Another example of multiple alleles is coat color in rabbits.
    • Here, four alleles exist for the c gene. 
    • The wild-type version, C+C+, is expressed as brown fur. The chinchilla phenotype, cchcch, is expressed as black-tipped white fur. The Himalayan phenotype, chch, has black fur on the extremities and white fur elsewhere. Finally, the albino, or “colorless” phenotype, cc, is expressed as white fur.
