  • Alleles found at the same locus.on homologous chromosomes,
  • Homozygotes (pure breds)
  • Heterozgote (hybrid)
  • Dominant Allele is expressed in a homozygote and heterozygote
  • Recessive Allele is only expressed in a homozygote.
  • Phenotype (appearance)
  • Genotype (combination of alleles)
  • Monohybrid Cross -one characteristic is used
  • Dihybrid Cross - two characteristics are used
