1. In a test cross for a tall (T) individual you should cross it with which genotype(s).
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?
Red b) Blue c) Both red and blue d) Purple e) Red, Blue, and Purple
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.
5. G is green while g is white. List the cross which will guarantee 50% of the progeny will be green and 50% will be white. EXPLAIN your answer.
