Answer:

- Alelos:  

Locus 1: A (alto); a (enano)

Locus 2: B (púrpura); b (blanco)

- Cruzamiento parental: AABB  x aabb

Genotipos F1: AaBb

- Cruzamiento F1: AaBb x AaBb

Fenotipo: 100% plantas altas púrpuras

- Genotipos F2:  AABB (1/16); Aabb (1/16); aaBB (1/16); aabb (1/16); AaBb (4/16); AABb (2/16); aaBb (2/16); AaBB (2/16); Aabb (2/16)

- Fenotipos F2: 9/16 A-B- (altas púrpuras); 3/16 A-bb (altas blancas); 3/16 aaB- (enanas púrpuras); 1/16 aabb (enanas blancas)

Explanation:

Un cruzamiento dihíbrido refiere a un tipo de cruzamiento entre dos parentales que difieren para  dos pares de alelos (AABB x aabb). Si consideramos dos <em>loci</em> de dominancia completa, un cruzamiento dihíbrido producirá una F1 heterocigota para ambos genes donde la progenie expresará ambos rasgos dominantes. Como resultado de la distribución independiente expresada en la segunda ley de Mendel, La F2 de este tipo de cruzamiento producirá un proporción fenotípica 9:3:3:1; es decir 9 individuos con ambos rasgos dominantes (A-B-), 3 con el rasgo uno dominante (A-bb), 3 con el rasgo dos dominante (aaB-) y 1 con ambos rasgos recesivos (aabb).
