Allele

frequencies of genes that are inheritable within a gene pool. They analyzed that the frequencies of alleles. Hardy and Weinberg made an equation about genetic variance of a population at equilibrium. They postulated that allele or genes should be stable or equal with no disturbing factors. For a generation be able to remain constant and reach the equilibrium within generations, they postulated about how alleles behave that acts in a population. With these assumptions, Hardy and Weinberg…

using two alleles to determine which will be present in future generations. This equation uses a Punnet Square that makes a mathematical format to interpret the information. This possibility is referred to as Hardy-Weinberg equilibrium or Hardy-Weinberg principle. Although the Hardy-Weinberg equilibrium is rarely met in a given population, it can occur if only the allele and genotype remain the same from one generation to the next in the absence of different evolutionary influences. Alleles…

The English Peppered Moth and Natural Selection Lab By: Justin Pascual Partners: Nathan Magbitang, Rudy Keyes-Krysakowski, and Glenn Tipold Teacher: Ms. Coopman Date Performed: November 16, 2015 The English Peppered Moth and Natural Selection Lab Purpose The purpose of this lab is to determine how variation in a population can favour survival of a certain trait over multiple generations. Hypothesis It is believed that if there are more speckled moths remaining in the tray at the end…

Drosophila melanogaster also known as the common fruit fly is mostly associated with fruits and vegetables, however it can originate from other sources. Drosophila melanogaster has a common life cycle of fifty days. In that time period female fruit flies lays several eggs. Similarly, fruit flies develop from larvae like other flies (Glick, Neimeier and Aiello). Drosophila melanogaster can reproduce anywhere that has fermented organic matter that stays moist. Fruit flies undergoes 4 (egg, larva,…

Meckel-Gruber Syndrome Meckel-Gruber Syndrome is a Fatal congenital autosomal recessive disease which is named after the German anatomist Johann Friedrich Meckel and the German physician Georg Gruber. This illness infects 1 in 13,250 to 1 in 140,000 people around the world; however, it’s more common in some regions. For instance, it was reported that Meckel syndrome has an incidence of 1 per 3,500 live births with a carrier rate of 1 in 30 in Bedouins in Kuwait (Teebi et al.1992). This…

1 INTRODUCTION Drosophila Melanogaster, also known as the fruit fly, is a most valuable organism in biological research that has made significant contributions particularly in genetics and research. It is used as a model organism in research for several reasons viz. Easily handled, sexually dimorphic, cheap and easy to keep large numbers, care and culture requires little equipments and well understood because of its short life cycle of just two weeks and also Entire genome of drosophila…

Blue People: Family of Troublesome Creek Martin Fugate and his wife Elizabeth Smith moved onto the bunks of Troublesome Creek, an area in Appalachian Kentucky. Martin and Elizabeth together had seven children. The family tried to hide out in the mountains because of the blood disorder that they carry with them. The blood disorder makes their skin turn blue. The blood disorder of how and why the family’s skin turns blue. Some facts about the blue people of Kentucky. The family has lived in the…

Traits are inherited in a variety of ways ranging from dominate or recessive and sex-linked or autosomal. Using different model organism, scientists are able to study inheritance patterns of many generations in a short period of time. Different model organisms are utilized in many different ways. In the case of this experiment, a model organism must have a rapid rate of maturation and reproduction. The use of Drosophila (fruit fly) was chosen for its fast gestation period and ease of trait…

For our table clinic we decided to research Marden-Walker syndrome. Marden-Walker syndrome is a rare inherited connective tissue disorder (3). This disease involves the oral cavity, facial features and other body parts. This disorder has distinct facial features that can allow you to differientiate this disease from others. Marden-Walker syndrome is a very rare disease. It affects males more often then females (4). There have only been twenty reported cases of this disease (4). Specific…
