Thus, genotypes have twice the number of letters because they must involve two alleles for each of the two traits. Epistasis . We will now consider a dihybrid cross, which is a combination of the two monohybrids. AaBb x AaBb, where offspring show the typical 9:3:3:1 ratio. The questions will mainly test you on the definition of dihybrid crosses. Gregor Mendel discovered the laws of inheritance by crossing pea plants with different traits like seed shape and color. Assume a cross is made between fruit flies with the following genotypes: aaBB and Aabb. When they perform the cross with their paper chromosomes they should find that the ratio is similar, though random chance will likely prevent it from being exactly the same.
