Barbara McClintock was a pioneer in the field of cytogenetics, and she left a lasting legacy of superb experimental inquiry. McClintock’s breeding experiments with maize are...
Throughout her career, Barbara McClintock studied the cytogenetics of maize, making discoveries so far beyond the understanding of the time that other scientists essentially ignored her work for more than a decade. But she persisted, trusting herself and the evidence under her microscope.
She produced the first genetic map for maize, linking regions of the chromosome to physical traits. She demonstrated the role of the telomere and centromere, regions of the chromosome that are important in the conservation of genetic information.

Feb 9, 2017 · Barbara McClintock conducted experiments on corn (Zea mays) in the United States in the mid-twentieth century to study the structure and function of the chromosomes in the cells. McClintock researched how genes combined in corn and proposed mechanisms for how those interactions are regulated.
The Nobel Prize in Physiology or Medicine 1983 was awarded to Barbara McClintock "for her discovery of mobile genetic elements". MLA style: The Nobel Prize in Physiology or Medicine 1983. NobelPrize.org. Nobel Prize Outreach AB 2024.
Mar 22, 2024 · In the 1940s, by observing and experimenting with variations in the coloration of kernels of corn, she discovered that genetic information is not stationary. By tracing pigmentation changes in corn and using a microscope to examine that plant’s large chromosomes, she isolated two genes that she called “ controlling elements.”
Sep 2, 1992 · Barbara McClintock studied corn's hereditary characteristics, for example the different colors of its kernels. She studied how these characteristics are passed down through generations and linked this to changes in the plants' chromosomes.
