We all have two alleles, or versions, of each gene. Being ​ (a)   for a particular gene means you inherited two identical versions. It's the opposite of a ​ (b)   genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.

• homozygous
• heterozygous

​ (a)   are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. ​ (b)   are expressed only if both the connected alleles are recessive.
