Report 1: Genetics-411 Population Genetics of Albinism in Zea mays Spring 2013 2/16/2013 Tory Thomason Introduction Zea mays or maize was chosen as the study system for this experiment for many reasons. The phenotype being studied is observable to the naked eye‚ green or yellow plants. It is an important agricultural system used in crop and is an ideal genetic model. Zea mays also has a quick turnaround time from generation to generation and crossing Zea mays

Prader-Willi Syndrome: An Investigation into Paternal and Maternal Origins & Characteristics Abigail McNeal Liberty University COUN 502- Professor Myers August 15‚ 2011 Abstract Prader-Willi syndrome‚ (PWS) is a genetic disorder that occurs in about one in every eight thousand births in the United States. PWS occurs when there is a defect or deletion in the fifteenth chromosome from either maternal or paternal origins. Individuals diagnosed with PWS need enhanced supervision to address the

Using P-element Induced Male Recombination to Generate a Deletion in the DMAP1 Gene on Chromosome Two in Drosophila melanogaster Abstract: The goal of this study was to induce a deletion in the DMAP1 gene on chromosome two in Drosophila melanogaster through P-element mobilization. The DMAP1 gene may be an essential gene‚ however not much is known about it. We attempted to uncover the function of DMAP1 by creating a series of genetic crosses and selecting for brown-eyed non-stubble male flies

family history and traditions. Identity defined in class notes- The development of identity involves finding out who we are‚ what we value‚ and where are we headed in life. Identity Formation is made up of many components: Physical (your race‚ phenotype dress etc) Social (including cultural‚ vocational‚ ideological‚ generational etc) Sexual (your orientation) Gender (which is sometimes physical and other times a mental construction) All of these contribute to something known as: Self Concept

Alfredo Salazar 1/28/2013 What have you learned? Chapter 1 1. What makes the study of human development a science? It seeks to understand how and why people‚ all kinds of people‚ everywhere‚ of every age‚ change overtime. 3. Why have recommendations regarding the sleeping circumstances of infants changed? Every year until the mid-1990‚ thousands of 2 to 4 month olds died of SIDS. Susan Beal hypothesized that sleeping position might matter‚ as a result‚ SIDS rate dramatically decreased.

The scientists consider the effect to be very unique. “The mutation is at a frequency of 26 percent in the Solomon Islands‚ is absent outside of Oceania‚ represents a strong common genetic effect on a complex human phenotype‚ and highlights the importance of examining genetic associations worldwide‚” said the abstract of the report. The team was stunned by their findings. “They have this very dark skin and bright blond hair. It was mind-blowing‚” Sean Myles‚ one of

thought to have caused the emergence of blond hair. Another valid hypothesis for the phenomenon was that blond hair evolved rapidly at a specific area at the end of the last ice age via sexual selection. The theory presents the possibility that the phenotypes of blond hair and blue eyes in some European women stood out from their adversaries in a time of competition for scarce males. According to the theory‚ this process of “sexual selection” spread to parts of Northern Europe‚ resulting in the modern

DISCOVERIES Gregor Mendel‚ also known as "The Father of Genetics" was an Austrian monk that made a huge discovery about genetics because of his mini garden full of pea plants. What made Mendel come to this experiment was because of the different phenotype or traits of the pea plants. Some were tall and some were short. Some plants either had purple or white flowers. Gregor observed each trait and saw how they were passed down to the offspring plants. After breeding plants‚ Gregor Mendel learned

According to Google‚ the definition of racism is the belief of all members possesses characteristics or abilities specific to that race. This definition gives a negative view to racism and slavery‚ and it should. The lingering effects of slavery and racism still haunt people today and will continue to do so for years to come. It all started when the first white people settled on America and they needed extra work for their farms. Now slavery and racism happens in school‚ jobs‚ homes etc. There are
