Punnett Square Example: Monohybrid Cross with Alleles A and a #117584 (License: Personal Use)

This image depicts a standard 2×2 Punnett square used in Mendelian genetics to predict offspring genotypes from a monohybrid cross between two heterozygous parents (Aa × Aa). The resulting genotypic ratio is 1 AA : 2 Aa : 1 aa, clearly labeled in each quadrant of the grid. The handwritten style emphasizes its use in educational settings like biology classrooms or study guides.

Used in biology education materials-textbooks, lecture slides, tutoring websites-to teach basic genetic inheritance. Matches user intent for understanding how dominant and recessive alleles combine in offspring.
