Solving Problems in Genetics: A Practical Report

1. Mendelian (Single-Gene) Inheritance

Step-by-Step Strategy

1. Determine dominance – Does the trait disappear in F1 and reappear in F2? (3:1 ratio → dominant/recessive).
2. Assign symbols – Use a capital letter for dominant, lowercase for recessive (e.g., A = unaffected, a = disease).
3. Write parental genotypes – If unknown, start with the recessive trait as aa and work backward.
4. Draw Punnett square – For monohybrid cross: 4 squares; dihybrid: 16 squares (or use branch method).
5. Calculate probabilities – Multiply individual probabilities along branches.

Solution:

• PDF Problem: "Pea plants with round seeds (R) and yellow seeds (Y)..."
• Your Variation: "Pea plants with wrinkled seeds (r) and green seeds (y)..." Solve it. If you get stuck, revert to the PDF’s logic.
