1. In Drosophila, the genes for body coloration and eye size areon different chromosomes. Normal-colored bodies are dominant toebony-colored bodies, and normal-sized eyes are dominant toeyelessness. Line A is true breeding for normal bodies and normaleyes, while line B is true breeding for ebony bodies andeyelessness. F1 flies are crossed and 352 F2 flies are produced.How many F2 flies are expected to have ebony body color and to beeyeless?
2. What is the probability that a plant of genotypeccWw will be produced from parentalplants of the genotypes CcWw andCcww? Assume that the two gene pairsdemonstrate simple dominance/recessiveness and that they assortindependently.
Type your answer as a decimal fraction with 3 significant figures(0.XXX).
3. Assume you cross dihybrids of Pisum sativum:R/r (round seeds) and P/p (purpleflowers). If you obtain 328 plants from that cross, what would bethe expected number of plants that would have the genotype:R/r, P/p?
