34. What is the probability that each of the following pairs of parents will produce the indicated
offspring (assume independent assortment of all gene pairs)?
a. AABBCC × aabbcc → AaBbCc
b. AABbCc × AaBbCc → AAbbCC

Trihybrid Crosses (Threetraits)
35. Using the forkedline approach and given the cross between two cats with the genotypes llSsdd
and LlSsDd, what is the probability of a cat having the genotype llssdd? What is the probability
of a cat having the short hair, white spotted, and nondiluted phenotype? [short hair is dominant
to long hair, white spotted coat is dominant to not spotted, diluted color is dominant to nondiluted coloring]
36. Using the forkedline approach in a trihybrid cross involving three traits, where the pigments are
both AaBbCc, what is the probability of their producing an offspring recessive for...
