Multiple Alleles
According to Mendel's model, each gene consisted of only a pair of two alleles. However, there are other special cases whereby a gene can have multiple alleles. For example, humans in a particular population can have different pairs of alleles. Most of the human traits result from multiple alleles. Examples of the multiple allele traits include the human blood type. The blood type allele traits are of three different types (A, B, and O) (Hartl, Clark & Clark, 1997). The A and B alleles are codominant. There are six possible phenotype combinations. They include the OO, AO, AA, BB, BO, and AB.
The inheritance is also manifested in other animals such as the rabbits. Rabbits have multiple alleles for determining their colour coats. The C gene is responsible for specifying the colour of the rabbit's fur. The C gene has four different...
