In 1983, Dr. Barbara McClintock was awarded the Nobel Prize in Medicine for her research on corn genetics. Kernels of Indian corn come in different colors, such as purple, yellow and white. Sometimes the individual grains are purple with white streaks. This streaked effect defies principles of genetics because individual grains may be multicolored rather than a single color. The movement of transposons on chromosomes may result in colored, non-colored and variegated grains that do not fit traditional genetic ratios based solely on chromosome assortment during meiosis and random combination of gametes. The explanation for this phenomenon involves jumping genes or what we now refer to as transposons. McClintock's work with transposons calls into question the model of inheritance patterns we have learned in the past that is the basis of Mendelian genetics. Which model would be MOST weakened by McClintock's discovery? A) A B) B C) C D) D
