  • Adding purple flowers and white flowers together will make some purple flowers and maybe some white flowers
  • If you repeat the process of adding purple and white flowers, taking away white flowers every time, you will get a true breeding line
  • Combining true-breeded purple flowers to white flowers will make all purple hybrids. If you combine purple hybrids with more purple hybrids, white flowers will slowly start to show up more.
  • A recessive trait is a trait that is hidden in any given generation.
  • Flowers being mixed first are the Parent Generation.
  • Flowers produced from the parent generation are called the first filial Generation (or F1)
  • Phenotype: observable characteristics, or traits
  • Alleles: An alternative form of a gene (i.e. R=rigid r=smooth)
  • Dominant alleles: mask recessive alleles
  • Recessive alleles: get masked by Dominant alleles
  • Genotype: The combination of alleles an organism has for a gene
    (i.e. HzD, Htrz, HzR)
  • Homozygous Dominant (HzD): Two dominant traits (PP)
  • Heterozygous (HtrZ): One dominant trait and one recessive trait (Pp)
  • Homozygous Recessive (HzR): two recessive traits (pp)
  • Dihybrid Cross: Tracking inheritance of two traits (i.e. YyRr x yyRR)
  • Phenotype Ratio - dominant : recessive (_:_)
  • Genotype Ratio - HzD : Htrz : HzR (_:_:_)
