a) TT b) Tt c) tt d) Either TT or tt
2. In many species of flowering plants, the gene(s) responsible for flower color are incompletely dominant. A cross of a red rose and a blue rose will create what color(s) of flowers?

3. T is tall while t is short. Which individual genotype guarantees all tall offspring. EXPLAIN your answer.
4. Explain the the difference in the relationship between alleles for a trait governed by incomplete dominance versus one governed by co-dominance.
