Punnett Square Example: Monohybrid Cross (Yy × yy) Explained #175465 (License: Personal Use)

This Punnett square demonstrates a monohybrid cross between a heterozygous parent (Yy) and a homozygous recessive parent (yy), resulting in two possible genotypes: Yy (dominant phenotype) and yy (recessive phenotype), each with 50% probability. The alleles are represented by yellow (Y, dominant) and green (y, recessive) leaf icons, visually reinforcing trait inheritance. The grid layout clearly shows allele combinations from gametes of both parents.

Used in biology education materials, genetics tutorials, or high school/college lesson pages to teach Mendelian inheritance; matches user intent for understanding Punnett squares, genotype ratios, and dominant/recessive traits.
