Heterozygous refers to a genotype where an individual has two different alleles for a particular gene. In this case, the person has one copy of each of two different alleles for a given gene, therefore, they are heterozygous for that trait. Homozygous refers to a genotype where an individual has two identical copies of the same allele, while recessive refers to an allele that is only expressed in the phenotype when paired with another identical recessive allele. True-breeding refers to a stable genotype that always produces offspring with the same traits as the parents.
