Gregor Mendel, an Austrian monk, introduced a new theory of inheritance based on is experiment with peas. Mendel’s genetic laws were called the Law of Segregation, the Law of Independent Assortment, and the Law of Dominance. Mendel worked with peas that were yellow or green in color and smooth or wrinkled in shape. The characteristics in the traits were distinct and similar; therefore, they gave Mendel the conception that his experiments would be easily tested. He concluded that the yellow pea plants, which bred with the green pea plants, had yielded all yellow peas; as a result, all the hybrid children looked like only one of the parents. Mendel theorized that genes can be made up of three possible pairings of heredity units called ‘factors’: AA, Aa, and aa. In Mendel’s crosses, the starting plants were homozygous AA or aa, the F1 generation was Aa and the F2 generation was AA, Aa, or aa. While Mendel’s research was with plants, the principles also applied to people and other animals. After Mendel’s death, his work was recognized, and he was regarded by the name ‘father of genetics’.

Gregor Mendel, an Austrian monk, introduced a new theory of inheritance based on his experiment with peas. He isolated true breeding strains of peas with distinctive traits to test his hypothesis about heredity being independent of the actions of an individual’s genome. Mendel concluded which member of a pair of genes became included in a gamete; he called this law ‘Law of Independent Assortment’. Mendel’s observations and conclusions also summarized another law called ‘Law of Segregation’, which states that one gene from each parent passes to an offspring. Mendel’s last law, ‘Law of Dominance’ states th...

...he pea plant traits that he studied were controlled by genes that do not exhibit an intermediate expression in the phenotype.

Gregor Mendel died, at age 62, on January 6, 1884. After Mendel’s death, his work was rediscovered by Carl Correns, Hugo de Vries, and Erich von Tschermak-Seysenegg. Although Mendel’s work was not recognized until the 1900s, he is still remembered and regarded as the father of modern genetics. Mendel’s genetic research with peas helped geneticists discover and develop new theories for Mendel’s unfinished work; therefore, the simple Mendelian genetics distinguished the environmental impact on phenotype, endured as the foundation of human genetics, and analyzed results for family histories. Mendel, along with his experiments and genetic laws, will always be credited as the man whose work prospered to new discipline within Biology and Genetics.

Essay about Gregor Mendel : Modern Day

- Gregor Mendel was an Austrian monk who studied how traits were passed from one generation to the next; his studies became the foundations of modern day though. “Many organisms…reproduce sexually.” Organisms that reproduce this way inherit a combination of genes from both of their parents and they will later pass these genes onto their offspring as well. Genes from both parents can be the same as well as code for different forms of a trait. These different forms are called alleles. The alleles that show depend on a large number of factors....   [tags: Genetics, Allele, Gregor Mendel, Dominance]

Essay about From Mendel to Monsanto

- GMOs first sprouted in the mid eighteen hundreds with an Austrian monk named Gregor Mendel breeding peas, and has now evolved into a worldwide method of creating the perfect plant. Companies like Monsanto and AstraZeneca lead the world of unlimited GMOs today. Although consumers are led to believe that genetically modified organisms (GMOs) in food crops are uncontrollable and harmful, GMOs can be controlled and can be considered to be extremely beneficial. One concern that numerous consumers have, is that GMO products will cause genetic mutations in both humans and animals that eat genetically modified crops , but such accusations are based on supposition and myth....   [tags: Genetically Modified Organisms, Gregor Mendel]

Essay on Biography of Gregor Mendel

- Biography of Gregor Mendel Gregor Mendel is considered the father of the discipline of Genetics. It is ironic that he bears this exposition, because Gregor Mendel never used the term gene or genetics in his life. It was not until 1905, twenty-one year after Mendel's death, that William Bateson baptized Mendel's work as genetics. Like many brilliant minds before him, Mendel was ahead of his era; his findings were ignored for nearly thirty years. Gregor was of peasant upbringings; his father was a farmer....   [tags: Papers]

Essay on Gregor Mendel 's Theory Of Genetics

- What is genetics. This is a common, simple question in today’s world. Genetics is simply put as the study of genes, what they do, and how they work. The science of and our current understanding of genetics has come a long way since Gregor Mendel’s pea experiments. Who is Gregor Mendel. Gregor Mendel is often regarded as the forefather to the genetics that we know today. If it was not for Gregor Mendel’s early pioneering in a subject that was practically rejected during that time period, who knows where genetics would be today and who knows what we would know.1,2 Gregor Mendel was born in Austria in 1822....   [tags: Genetics, Gregor Mendel, Pea, Flowering plant]

Essay about Gregor Mendel : The Modern Science Of Genetics

- Gregor Johann Mendel was a German-speaking Moravian scientist and Augustinian friar who gained posthumous fame as the founder of the modern science of genetics. Though farmers had known for centuries that crossbreeding of animals and plants could favor certain desirable traits, Mendel 's pea plant experiments conducted between 1856 and 1863 established many of the rules of heredity, now referred to as the laws of Mendelian inheritance. Mendel worked with seven characteristics of pea plants: plant height, pod shape and color, seed shape and color, and flower position and color....   [tags: Gregor Mendel, Genetics, Pea, Charles Darwin]

Gregor Mendel's Fruit Flies Essay

- Gregor Mendel's Fruit Flies Introduction      From simple heredity experiments with garden peas, to cloning sheep, the field of genetics has come a long way. Now we are closer to mapping out the human genetic map due to advances in technology, and years and years of research. Perhaps the most influential and groundbreaking scientist, Gregor Mendel, he was responsible to provide a path to where genetics is now today with his experiments of garden peas.      In lab, fruit flies were crossed to observe inheritance patterns in their offspring....   [tags: Biology Gregor Mendel Essays]

Essay on Gregor Johann Mendel

- Gregor Johann Mendel Gregor Mendel was one of the first people in the history of science to discover genetics. He independently discovered his work and lived in Brunn, Czechoslovakia. In Brunn he was a monk and later the Abbot of the church in Brunn. While he was in Brunn he performed many experiments with garden peas. With the information he observed he wrote a paper where he described the patterns of inheritance in terms of seven pairs of contrasting traits that appeared in different pea-plant varieties....   [tags: essays research papers]

Essay on Gregor Mendel

- Gregor Mendel played a huge role in the underlying principles of genetic inheritance. Gregor was born, July 22 1822 in Heinzendorf, Austrian Silesia (now known as Hyncice, Czech Republic), with the name Johann Mendel. He changed his name to Gregor in 1843.

Essay on Gregor Johann Mendel

- Gregor Mendel was born in Heinzendorff in 1822 and died in 1884. Ever since Mendel was a boy he was very interested in science. Whenever his friends would come back from school they would tell Mendel what they studied and he would be so excited. Mendel was so interested about what his friends told him that he begged his father to let him study. This meant a great sacrifice to his father he because owned a small farm. Needless to say, he sent his young son Gregor, who was only eleven to school. At school Mendel showed great intelligence so much that his parents decided to deny themselves the pleasures of life to keep their son in school....   [tags: essays research papers fc]
