These allele combinations can produce traits with more than two possible outcomes. The ABO blood group system is a...

Genes can exist in different forms called alleles, and these alleles control variations in inherited traits.

Some genes have more than two alleles in a population, which creates multiple possible genetic combinations.

Even when many alleles exist in a population, each individual inherits only two alleles for a specific gene, one from...
