GENETIC CROSSING

• GENETIC CROSSING

  • the intentional breeding of two selected, different individuals, resulting in offspring with half of each parent's genetic makeup. 
• Monohybrid cross: defined as the cross happening in the F1 generation offspring of parents differing in one trait only.
• Dihybrid cross: defined as the cross happening in the F1 generation offspring of parents differing in two traits
• STEPS IN THE MONO/DIHYBRID GENETIC CROSSING

  a.Identify the parent’s allele

  b. Create a punnett square

  c. Identify the genotype

  d. Identify the phenotype

  e. Genotypic ratio

  f. Phenotypic ratio

  g. Probability
