Definition of heterozygous. : having the two alleles at corresponding loci on homologous chromosomes different for one or more loci.
Best Answer: Heterozygous is when you have 2 different alleles for a certain characteristic: e.g. You could have a gene for brown eye colour on one chromosome and a gene for blue eyes on the other. In this case the dominant gene of the 2 would be expressed in the individual. Homozygous dominant is when the 2 alleles are the same and they are the dominant form of the gene. e.g. 2 brown eye genes BB Homozygous recessive is when the 2 alleles are the same and are the recessive form of the gene bb.
