A student has a group of corn plants with long stalks, and a group of corn plants with short stalks. She crosses the long stalk and short stalk plants. The resulting generation of corn plants all have short stalks. Based on this experiment, what can the student determine about the alleles for stalk length? A. Short stalks must be recessive, because the short stalk trait was hidden in some of the offspring.

B. Short and long stalks are both dominant, because both traits were present in the parent plants.

C. Short stalks must be dominant, because the short stalk trait covered up the long stalk trait in the offspring.

D. Long stalks must be dominant, because the long stalk trait was present in one of the parent plants.

Taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? view available hint(s)taq polymerase is an enzyme isolated from the organism thermophilus aquaticus. this organism has been found living in the hot springs of yellowstone national park. this enzyme is used to copy human dna from crime scenes. most reactions are performed at ranges similar to those of the human body; however, what considerations should be made for optimum use of this enzyme? the enzyme will not work on human dna. nothing should be altered. the ph should be decreased. the temperature should be raised.
