SEE Science Genetics: Mendel's Laws, Monohybrid Crosses & Punnett Squares

Heredity questions in SEE Science follow strict Mendelian inheritance patterns that can be formatted as clean Punnett squares.

The 4 Key Presentation Steps

1. Define parent phenotypes and genotypes (e.g., Pure tall $TT \times$ Pure dwarf $tt$).
2. Show gamete separation ($T$ and $t$).
3. Construct a $2 \times 2$ or $4 \times 4$ Punnett square for $F_1$ and $F_2$ generations.
4. State both phenotypic ratio ($3:1$) and genotypic ratio ($1:2:1$) clearly.
