Mendel’s First Experiment: Monohybrid Cross & Inheritance Patterns #175487 (License: Personal Use)

This diagram illustrates Gregor Mendel’s monohybrid cross experiment using pea plant seed shape-smooth (dominant, S) versus wrinkled (recessive, s). The parental generation (SS × ss) produces uniformly heterozygous F1 offspring (Ss), all expressing the dominant trait; self-pollination of F1 yields an F2 generation with a 3:1 phenotypic ratio, visualized via a Punnett square. The image clearly shows segregation of alleles during gamete formation and their recombination.

Used in biology education materials, textbooks, and online learning platforms to teach Mendelian inheritance, allele segregation, and Punnett square analysis. Matches user intent for understanding basic genetics concepts, homework help, or lecture preparation.
