  6. Genetic Terms • Genetics- thescienceofheredity, study of genes • Allele- anyofseveralformsofagene (a single letter) • Dominant- the allele that ‘masks’ the recessive allele • Recessive- the allele that is ‘masked’

  7. Genetic Terms • Trait- aninheritedcharacteristic • Monohybrid Cross- agenetic cross made to examine the distributionofonespecific set of alleles in the resulting offspring. • Genotype- the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complexoftraits. • Phenotype- theappearance of an organism resulting from the interactionofthegenotypeandthe environment.
