Biology Barbara McClintock McClintock was a research scientist who studied how chromosomes in maize changed and how they underwent transformation during their reproduction stages (Spangenburg & Moser 35-41). Through her laboratory research, she was able to develop a groundbreaking method of observing maize chromosomes as they developed. Spangenburg & Moser write that she used microscopic inquiry to explain different genetic developments (35-41). By narrating the process of genetic recombination during meiosis, she developed a maize genetic map.

Finally, she elaborated on the role of centromere and telomere the central part of genetic transformation in maize (Spangenburg & Moser 38). Using the developed theories, she was able to explain the control and genetic development of a given maize generation to another generation. Finally, she conducted a study of ethnobotany and cytogenetic of maize race in different settings (Spangenburg & Moser 96). This study was important because McClintock was a pioneer in cytogenetic use maize as her study specimen.

Walter Sutton Sutton was not interested in medical biology. However, he described the connection between chromosome and inheritance (Crow & Crow 1-4). He discovered the importance of chromosomes in the testicles of a grasshopper. These chromosomes were said to be inherited genes (Crow & and Crow 4). This discovery formed a basis of modern microbiology today. Hermann J. Muller Muller was a geneticist who examined the genetical and physiological impacts of radiation (Foster 72). This study was important because it created public awareness of the impacts of nuclear radiations.

He published several articles on scientific knowledge among the learned communities. Carl Correns Finally, Correns was German geneticist and botanist, who discovered the principles of hereditary in biology. He further rediscovered Mendel’s finding on hereditary, and he greatly disregarded Mendel’s discovery (Watson 23). In his findings, he restated Mendel’s findings and used his principle of independence and segregation to describe the law of inheritance (Watson Part 3). Works CitedCrow, Ernest & Crow James.
