1. Compare chromosome maps and physical (sequence) maps by defining their basic principles.( (15 points) 2. In Kansas, a farmer is growing a variety of wheat called TK138. In Poland another farmer is growing another variety of wheat called UG334. The yield of UG334 is only about 40% of the yield of TK138. The narrow-sense heritability for TK138 is 0.95. Considering narrow sense heritability value, is it logical to plant TK138 wheat in Poland? Explain your answer thoroughly. (Explain also narrow sense heritability). (15 points) Indicate if the given phrases are true (T) or false (F). Explain your answer. (If you answer only as true (T) or false (F), you cannot get any point. Write at least 2 sentences to explain. ) (7 points/each) ********* 3.
