MULTIPLE ALLELES


Certain traits, such as blood types, hair color, and eye color, have more than two allels that are found in an animal population. Although each individual only has two alleles, there can be many different alleles in that same population.

For instance, if mice color can be black, yellow, or agouti (combination of colors), and inheritance is due to multiple allels, what is the phenotype of the offspring from a cross of heterozygous yellow to a heterozygous black?

In this case, black is dominant over all, and the agouti color is only visible with homozygous recessive.
