• B. Pisum, Barbara McClintock
• C. Zea mays, Guha and Maheshwari
• D. Lillium, Guinguard

Answer 1

The correct option is A Zea mays, Barbara McClintock

Jumping genes are the DNA sequences that can move (or jump) from one location in the genome to another. Barbara McClintock discovered jumping genes in Zea mays. Their movement may cause mutations and also can duplicate or reduce the amount of DNA in the genome of the cell. If the duplication or deletion occurs in gametes, the change is inherited to offspring. Correct answer is option A.
