If an individual has two recessive alleles for the same trait, the individual is said to be homozygous recessive for that trait. In genetics, alleles are different versions of a gene. Genes reside on chromosomes, and each gene controls specific characteristics or traits. Humans have two sets of chromosomes, one set from each parent, hence two copies of each gene. When the two copies (alleles) of the gene are the same and they are the recessive version, the trait associated with the recessive allele will be expressed in the individual.
For example, if the gene associated with a certain trait (such as eye color) has a dominant allele (represented as "B") and a recessive allele (represented as "b"), an individual with two recessive alleles ("bb") will exhibit the trait associated with the recessive allele.
