In order to confirm the findings of Mendel’s laws, we conducted a dihybrid cross of Brassica rapa Fast Plants. Among the parent progeny was a homozygous sample for non-purple (aa) stems and yellow-green (yy) leaves. It was crossed with an unknown sample with non-purple stems (aa) and green leaves (Yy or yy). Once we provided the plants with a proper environment to allow growth, the F1 progeny displayed the phenotype we had predicted with non-purple stems and green leaves. DNA had then been extracted from P1, P2, and F1 progeny using a Zymo Plant/Seed DNA Mini Prep Kit. Using PCR, the DNA from the samples had been amplified in the agarose gel image. Our gel images displayed two bands for our P1, P2, and F1 DNA samples. Due to the fact that the F1 progeny phenotype and genotype confirmed our initial hypothesis we can verify the principles of Mendel’s laws.
INTRODUCTION
The discoveries uncovered by Gregor Mendel have since altered the way that researcher’s understand inheritance and genetics. Through the experiments he conducted on the P. Sativum he was able to cultivate a better understanding of the relationship between hereditary traits and genetics (Pierce 2014). After years of experiments, Mendel was able to generate principles relating to the inheritance that has since been referred to as Mendelian Laws. Among these laws is the principle of segregation, which deduces that an individual diploid organism has two alleles for a characteristic and one allele from each parent is given to their own gamete. The alleles then separate in equal proportions when the parent gametes are combined to fertilize. Through this finding and the use of monohybrid crossings, Mendel was able to uncover the mystery of dominant and recessive traits. Anot...

...needs to be an optimal environment for their growth to occur within 40 to 45 days. A place that provides continuous fluorescent light such as a light bank should be used. The light sources must be placed in an area that will implement a constant temperature. The temperature should remain within 65 to 78 °F. To be able to plant the seeds, it’s important to use the correct potting mix and fertilizer that will help the plant to grow within the ideal time frame. Included in many fast plant kits is a light potting mix that allows for aeration (Fastplants.org). In order for the fast plants to grow quickly, a continuous supply of water must be provided. We had put just enough water so that it begins to leak from the bottom of the pot, which is approximately 1-2 inches. It was up to group members to regularly check on if the water levels were adequate (Fullerton 2015, p.12).

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

- 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. He grew up in an Augustinian brotherhood and he learned agricultural training with basic education. He then went on to the Olmutz Philosophical Institute and later entered the Augustinian Monastery in 1843. After 3 years of theological studies, Mendel went to the University of Vienna, where 2 professors influenced him; the physicist Doppler and a botanist named Unger....   [tags: essays research papers]

Mendel 's Laws Of Inheritance Essay

- Gregor Mendel was born into a German family, as a young man Mendel worked as a gardener and studied beekeeping. In his later life Mendel gained his fame as the founder of the modern science of genetics. The research that was his claim to fame was his pea plant experiment. Mendel looked at seven different characteristics of the pea plants. For example with seed colors when he bred a yellow pea and green pea together their offspring plant was always yellow. Though, in the next generation of plants, the green peas reemerged at a 1:3 ratio....   [tags: Genetics, DNA, Gregor Mendel, Pea]

Mendel 's Two Laws Help Us Understand And Analyze Genetic Crossings Essay

- When trying to understand genetics Mendel 's laws are a very big part of it. Mendel 's two laws help us understand and analyze genetic crossings. In our experiment we used drosophila melanogaster flies, a common fruit fly. This was perfect to understand and visualize how the laws take effect. Mendel stated that during the process of genetic crossing; two alleles are formed which then separated to form gametes, which would appear in fertilization. In our experiment we accomplish a cross that determined different eye and body colors....   [tags: Gregor Mendel, Genetics, Allele]

Gregor Mendel, An Austrian Monk Essay

- 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....   [tags: Gregor Mendel, Genetics, Allele, Dominance]

The Importance of Mendel’s Laws in Modern Genetics Essay

- The Importance of Mendel’s Laws in Modern Genetics - Human genome is like an intricate library that stores vast volumes of life information. The preservation and passage of genetic books to future generation is one of the primary tasks of human genome. In the late 19th century not too long after the library of Congress was built in the United States, Gregor Mendel, an Austrian teacher and abbot, made a keen observation in the garden of a monastery at Brno. After testing and breeding 28,000 pea plants, Mendel discovered the mathematic pattern of describing how parents pass on their traits to the offspring....   [tags: Genetics]

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]

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]

- Mendel's Peas and Hawkweeds Works Cited Missing Many Scientists have contributed to the field of genetics. Yet the groundwork for today's modern genetics can be found in the work done by one man, Gregor Mendel. While there were many scientists who tried to answer the same questions before him, none were able to come to the successful conclusions he did. Before Mendel's experiments, many other theories had been in place to answer the questions about why we look like our parents. Many of these beliefs were myths, and the true reasons behind heredity were not sought, because creation was the belief of the majority of people....   [tags: Heredity Genes Mendel Research Essays]
