Teosinte is native to:

Based on a molecular clock analysis, how long ago did the common ancestor of modern corn and teosinte live?

Several varieties of Teosinte grow throughout Mexico and Central America. DNA analysis showed that the variety most similar to modern corn is native to the:

George Beadle crossbred 50,000 F1 hybrids and determined that teosinte and corn differed by:

To figure out how many altered genes were involved in the transformation of teosinte into corn. Beadle crossed corn and teosinte plants. He then crossed the F1 hybrids. What did he look for in the F2 generation? 

Rollins Emerson was George Beadle’s major professor at Cornell. Emerson is important in genetics for rediscovering the laws of inheritance established by:
