Recessive Trait- a characteristic that is visible only when two recessive alleles for the same trait are inherited 10. Homozygous- an organism that carries two dominant or two recessive alleles for a particular trait (tt, TT) 11. Heterozygous- an organism that carries both a dominant and a recessive allele for a particular trait (Tt) 12.
