Genetic Analysis in Plants Trev Mumm and Peter Masinelli Life 120 – Lab Section 122 April 28th, 2014 ABSTRACT We completed this lab to classify and count phenotypic traits in plant crosses with one or two segregating mutations, and we also learned how to use the Chi-Square test as a tool to access the statistical significance data collected from a genetic cross. Our hypothesis for the experiment that included green and albino corn genetics, was that the ratio of green to albino…
friends with two of his professors, Friedrich Franz who was a physicist and Johann Karl Nestler who was an agricultural biologist, who were also interested in heredity. Mendel’s monastery had a five acre garden where two former professors encouraged Gregor to pursue his interest in heredity by using the garden for his experiments. The main theory during Mendel’s time was that offspring were just a combination of the traits expressed in their parents. Mendel set a very ambitious task of…
Mendelian inheritance is centered around three laws discovered by Gregor Mendel. First is the law of segregation which states that during the formation of gamete the two allele pairs separate randomly. The second law is independent assortment which states during gamete formation each pair of the allele will segregate independently of the rest of the pairs of the chromosomes. The third law is the law of dominance which is that alleles can be dominant or recessive with the expression of the…
Once Upon a Dime: A Math Adventure is a tale targeted towards elementary grades, to teach about the value of money. The story is told by a boy, whose name was never revealed, who enjoys working on a farm with his neighbor, Truman Worth. One day, Mr. Worth notices a sprout growing in an unusual spot. He makes his own organic fertilizer, and decides to use it to help the sprout grow. By the next season, they notices that pennies are growing from the plant. Overjoyed, they decide to continue using…
Confirmation of Mendel’s Law of Segregation I. In Biology class the past few weeks we have been learning about Gregor Mendel. Gregor Mendel is often called the father of modern genetics. Mendel developed the theory of inheritance several decades before the observance of chromosomes via microscope. In Biology lab the past two weeks I completed a series of tests using fast plants, Brassica rapa. The objective of this experiment was to study the Mendelian laws of genetics as they applied to…
Since the dawn of cognitive thought, human civilizations have sought to understand the inheritance of certain physical traits from parents to their offspring. The limited knowledge of the true mechanism of inheritance remained elusive for many generations. The role of inheritance was clear, as seen with selective breeding of livestock and plant life. This could be seen by, breeding two parental types that had specific desirable traits and getting the desired results in offspring, most of the…
1. Objective The objective of this lab is to test whether the dominant phenotype in flies is actually straight wings red-eyed using data stimulated from the FlyLab software. Hypothesis The mode of inheritance in flies is that red eyed, straight winged flies are the wildtype characteristics that are autosomal dominant and white-eyed, vestigial wings are the mutated characteristics. 2. Methods a. Performed a cross between a red-eyed straight winged female fly and a white-eyed, vestigial winged…
Gregor Mendel lived during the early 1820’s till the early 1840’s. He grew up on a farm in rural Austria, consequently education was not always the top priority. A teacher noticed his capabilities, and recommended a higher level of schooling, Gregor flourished in his studies, and became a monk. While being a monk, he was sent to a university in Vienna to further his studies. Mendel discovered genetics and heredity after experiments with a pea plant in his garden. He decided on pea plants based…
Gregor Mendel the famous scientist who experimented with pea plants to get a better understanding of genetics. As much work he did with pea plants he was also a botanist. His observation became the root of the study of heredity. His work showed that genes in pea plants follow certain patterns. Like all experiments Mendel had to have a hypothesis, the experiment and the results. Gregor Mendel experimented with genetics to understand why offspring look the way they did. He started his experiments…
Gregor Mendel wearied the garden pea as the susceptible in his hereditary studies. In antithesis to anterior cultivate breeders, hellos review complex stop-blending characteristics of the field pea. Mendel applied mathematics, followed the scientific means really closely, plus kept thoughtful albums. Hellos upshots supported a particulate speculation of endowment, efficiently disproving the blending idea of patrimony. Further formats of endowment get been found hence Mendel’s indigenous gift.…
