Homozygous vs Heterozygous Genotypes in Pea Plants - Genetic Inheritance Example #117588 (License: Personal Use)

The image illustrates two tall pea plants grown side by side: one with genotype TT (homozygous dominant) and the other with Tt (heterozygous), both expressing the dominant tall trait. Though genetically different, their identical outward appearance highlights how a single dominant allele (T) is sufficient to produce the same phenotype. This classic example reflects Gregor Mendel’s foundational experiments on inheritance patterns.

Used in biology education materials, genetics textbooks, or online learning modules to explain genotype-phenotype relationships, dominance, and Punnett square predictions; targets students and educators seeking visual reinforcement of Mendelian principles.
