What are Genetics

Genetics is the study of the variation of inherited characteristics. It is the study of why living things have certain characteristics such as eye color, ear shapes, and nose shapes. Genetics are passed from one generation to the next.

Gregor Mendel

Mendel was alive from 1822 from 1884. He was German speaking. He was an Austrian monk. He was the founder of the modern science of Genetics. Gregor is the middle child of two sisters. His father's name was Anton and his mother's name was Rosine. After Gregor was schooled in his home village, his parents decided to send him away to another school to get a secondary education. Gregor attended the University of Olomouc. There, he studied philosophy and physics from 1840-1843. In 1843 he began training for a priest at the Augustian Abbey of St Thomas in brno. The monastary then sent Gregor to the University of Vienna. There he studied physics and mathematics. In 1853 he rejoined the monastary. Gregor Mendel died on January 6, 1884.

In 1856 he decided to start his study on plants. His pea plant experiments established many rules of heredity. Heredity is now referred to as the laws of Mendelian inheritance. He recognized 7 distinct characteristics in edible pea plants that remained consistant for generations. The characteristics of the plants included everything with the shape, color, and size. He crossbred plants to study the affects of the offspring. Over 8 years he made many observations about plants that form a deeper study of Genetics. He presented his experiments and they were soon published in the paper but at the time it didn't interest anyone.

Mendel connects to Genetics because he is known as the Father of genetics. At the time, he did years of experiments to bring him into the conclusion of a deeper, more complicated form of Genetics. He has almost everything to do with Genetics.

Alfred Day Hershey

Alfred Day Hershey was born December 4, 1908 in Owosso, Michigan. His father was Robert D. Hershey and his mother was Alma Wilbur Hershey. Hershey went to Michigan State College and there he got his Bachelor in Science Degree in Chemistry in 1930. He also got his doctorate from the same college. He married Harriet Davidson Hershey and they had one child, Peter Manning Hershey. Alfred died on May 22, 1997.

After recieving his doctorate, Hershey started working as an instructor in the Department of Bacteriology and Immunology at the Washington University School of Medicine at St. Louis. He worked a total of 16 years at the Washington University. Just after four years of working as an instructor, he was promoted assistant professor in 1938. Then in 1942, he was awarded associate prefessor. In the 1940's Hershey conducted his own experiments and was invited to share his work with Max Delbruck and Salvador Edward Luria. Later on, Hershey and Delbruck discovered "genetic recombination". After the discovery, Hershey transfered from ummunology to genetics. He then moved to New York and discovered his famous "blender experiment" with his assistant Martha Chase. In 1962 he became Director of the Genetics Research Unit of the Carneige Institution and continued his research on genetics. He retired in 1974 but still continued to make regular visits to the lab.

Hershey relates to my topic of genetics because he studied genetics deep in depth and conducted many experiments dealing with genetics.

Barbara McClintock

Eleanor McClintock aka Barbara McClintock was born on June 16, 1902 in Hartford Connecticut. Her father was Thomas Henry and her mother was Sara Handy McClintock. She spent most of her child with relatives and after grauating high school in 1919, she attended Cornell University. She earned her bachelor's degree in Botany in 1923. She was awarded a Ph.D. in 1927 after working with Lowell Fitz Randolph and Lester W. Sharp. She died on September 2, 1992 in Huntington.

During 1930-1931, McClintock worked with botanist Harriet Creighton and they made a major breakthrough in chromosomal crossover and and recombination of genetic traits. They published their work. In 1931 Barbara created the first genetic map. Then during the years of 1931 to 1932 she started working with Lewis Stadler in Missouri. They then used x-rays as mutagen for her studies on genetics. She explained the arrangement of DNA sequence. In 1933 she studied the non-homologous recombination of genetics material. From 1934 to 1936 she continued her research work at Cornell University. In 1936 she started working as an Assistant Professor at the Unviersity of Missouri. She continued her work in genetics at the Cold Spring Harbor Laboratory in the Carneige Institution. In 1944 she became the thrid woman to be inducted in the National Academy of Sciences. She was also named the President of Genetics Society of America. In 1953 she published a paper on Genetics which developed into theories. Throughout he 60's and 70's she continued her work in Central America. In 1967 she was named scientist emeritus at the Carneige Institute of Washington.

Barbara McClintock is related to genetics because her entire life she studied genetics and invented many things that deals with genetics. She was named President of Genetics Society of America so she has a lot to do with the invention of genetics.
