6 True/False questions

  1. Recessivethe entire genetic makeup of an organism; also the combination of genes for one or more specific traits (uses letters in problems)

          

  2. Incomplete dominancea condition in which a trait in an individual is intermediate between the phenotype of the individual's two parents because the dominant allele is unable to express itself fully (different dominance)

          

  3. Genotypethe entire genetic makeup of an organism; also the combination of genes for one or more specific traits (uses letters in problems)
