Allele

Lactase persistence is the result of a gene mutation and therefore considered the mutant allele while non-persistent is the wild-type allele. However, the LCT gene itself is not mutated. The single base pair mutation (a change from a “C” to a “T”) occurs in an intron of a neighboring gene that lies 13,910 nucleotides upstream, which alters the process in which the…

distinguishing between wild type and vestigial wing phenotypes. We also determined whether the allele that caused the vestigial wing phenotype is sex- linked or autosomal and either dominant or recessive from flies that were in the F1 generation. Our data collected by observing the sex of the F1 generation and creating a punnett square suggested that the allele for vestigial wings is an autosomal, recessive allele. From the inheritance pattern that we found, we were then able to determine the…

Albinism is a rare genetic condition characterized by the reduced pigmentation in a person’s hair, skin, and eyes. In most variations of the disorder, it is an autosomal recessive condition, an albino individual would have to inherit the recessive allele from both parents. This condition has been of particular intrigue to me ever since I had been introduced to the disorder when reading a novel where the main character suffered from albinism. Even though this character had suffered extreme…

Aceruloplasminemia We learned about many What is it? Explain/describe the general symptoms of your choice. Best described as iron accumulation in the body, aceruloplasminemia is a genetic disorder where iron accumulates in organs. This bc of such, it is classifed as a neiodgentiv disirder Symptoms typically manifest during adulthood approximaentl y 85% of synomatic patients are also diagnosded with anemia, 80% with diabetes, 77% with reRetinal degeneration, and Neurologic symptoms…

Olivia Olson Dr. Alex Hill Bio A 348 9 December 2016 Tay-Sachs: Why so Selective? There are aspects of nature that puzzle the world. Scientists, as curious as they are, try to figure out and solve nature’s great mysteries. One biological phenomenon that appears is Tay-Sachs disease. This is a disorder that tends to appear in only a handful of populations around the world. For quite sometime it was a mystery as to why this deadly disease tended to only show up in certain populations; but thanks…

Meghan was two when her father was diagnosed with Huntington's. At the time, she didn't understand what that was. In 2006, in College, while pouring herself some lemonade, she spilled the pitcher and knocked her glass on the floor. When her mother was helping her clean up the mess, Meghan told her she thought she had Huntington's disease. Her mother has seen the symptoms for a few years, and she finally told her that she knew. Then she went to get her test done (Caring Voice Coalition).…

In protein synthesis there are 3 to 4 structures that occur. In the primary structure there are covalently bonded sequences of amino acids and this happens through dehydration synthesis where complex molecules are broken down to simple components. Secondary structure happens within the protein and can repeat multiple times and this happens from the folds by the Hydrogen bonds. Finally, you reach tertiary structure where the final 3-dimensional shape is shown by the complete polypeptide chain.…

each type. We used this data to calculate the chi square value, which we compared to the table to determine whether or not the hypothesis was true. INTRODUCTION The law of segregation states that alleles of a trait separate independently during gamete formation such that each gamete receives only one allele from each allelic pair. Genetic traits are passed down from one generation to the next in different ways. For example, autosomal inheritance is a pattern in which transmission of the trait…

Chromosomal inheritance relates to how a person has 2 sets of chromosomes, 46 in total, that they inherited their parents. Chromosomes carry the genes, particularly the alleles that the offspring inherit. Gregor Mendel had no understanding of chromosomes when conducting his studies. He experimented and tested peas and discovered that some genes were dominated (showed up) while others were recessive (hidden). What he didn’t know was that chromosomes contained the genes that were responsible for…

1. In your own words, define what is a mutation? Abnormal inherited or acquired permeant alteration in the sequences of the nucleotides of the deoxyribonucleic acid of an organism may or may not change organism phenotype, it occurs with a frequency of less than1% among a population. 2. Are mutations bad or good for you? Justify your answer in either case Mutations could be good, bad, or may have little or no effect. Beneficial mutations: Some mutations if they happen they have a positive…
