Corn dihybrid cross
WebDihybrid Cross in Corn Corn is not only a commercially important crop. It has also been a valuable organism used in basic genetic studies to understand genetic principles. Geneticists such as Dr. John Osterman, in the School of Biological Sciences at the University of Nebraska, use corn in basic genetic studies. Let’s examine one experiment.
