If the problem doesn't state dominance, look for "true-breeding" parents whose offspring all look the same; that trait is dominant. 2. Determine Parental Genotypes Determine the Genotype and Phenotype : Determine the

  • Determine the Genotype and Phenotype: Determine the genotype and phenotype of the parents and offspring.
  • Use Genetic Terminology: Use genetic terminology, such as dominant, recessive, homozygous, and heterozygous, to describe the genotypes and phenotypes.
  • Calculate Probabilities: Calculate the probabilities of different genotypes and phenotypes using the Punnett square.
  • Check Your Answer: Check your answer to ensure it makes sense and is consistent with the information provided.
  • Draw a Punnett Square: Draw a Punnett square to visualize the possible genotypes and phenotypes. This will help you to:

    He added his own problem, the final one: “Problem #129: You have a PDF. It contains no final answers. You have a granddaughter with a disease that has no cure. What do you do?”

    | Pattern | Typical ratio | Example | |---------|---------------|---------| | Incomplete dominance | 1:2:1 | Red (RR) × White (WW) → Pink (RW) | | Codominance | 1:2:1 | Blood type MN (both M and N expressed) | | Lethal alleles | 2:1 | Yellow mice (Aa × Aa) → 2 Aa : 1 aa (AA dead) | | Epistasis (recessive) | 9:3:4 | Labrador coat color (B_E_ = black, bbE_ = brown, __ee = yellow) | | Epistasis (dominant) | 12:3:1 | Summer squash color |
