Punnett Square Basics (detailed) — free printable clipart

About this illustration

A detailed, fully-labeled infographic poster explaining Punnett Square basics. It is divided into seven numbered sections: (1) What Is It? — defines a Punnett square as a chart used to predict possible genotypes of offspring, illustrated with a seedling; (2) Example: Bb × Bb — shows a completed 2×2 Punnett square with Parent 1 alleles B and b across the top and Parent 2 alleles B and b down the side, producing cells BB, Bb, Bb, bb; (3) How It Works — four-step flowchart: write parents' genotypes, find possible gametes, set up a 2×2 square, fill in the square; (4) Key — defines dominant allele (uppercase B, masks recessive) and recessive allele (lowercase b, expressed only when no dominant allele is present); (5) Results — shows BB at 25% (1 out of 4), Bb at 50% (2 out of 4), bb at 25% (1 out of 4), genotype ratio 1 BB : 2 Bb : 1 bb; (6) Early Trait Example — uses plant height, crossing Bb (Parent 1) × Bb (Parent 2); (7) Remember — four reminder statements about Punnett squares predicting probabilities, each square representing one possible outcome, results explaining inheritance, and practice improving prediction skills.
