Punnett Square Example: Tt × tt Cross Explained #117581 (License: Personal Use)

The diagram displays a standard 2×2 Punnett square for a monohybrid cross: the top row labels represent gametes from a heterozygous parent (T and t), while the left column shows gametes from a homozygous recessive parent (t and t). Each of the four resulting cells contains “Tt”, indicating that 100% of offspring will be heterozygous dominant in genotype, though phenotypically they will express the dominant trait. This visual reinforces Mendelian inheritance principles for introductory genetics education.

Used in biology textbooks, online learning modules, or classroom slides to teach basic Mendelian genetics, specifically monohybrid crosses involving dominant and recessive alleles; matches user intent for understanding genotype prediction and inheritance outcomes.
