Allele Gamete Zygote Phenotype

Scientific rule used: each parent contributes one allele through a gamete. The offspring genotype is formed by combining one gamete from each parent. Visible traits depend on the inheritance pattern.

Important: this is a single-gene teaching model. Real traits can involve many genes, environment, linkage, epistasis, and mutation. This model deliberately shows the classic Mendelian core logic.
