Earlobe Allele Frequency Lab Report

My observations of human behavior were made at Starbucks on Grand avenue, New York near Elmhurst. I chose this location due to the high customer traffic that it sees. Since it is a popular coffee shop, the customer base cuts across different multicultural sector of the population. There is a lot of variety in the backgrounds and personalities of the people visiting the shop. This quality makes any patterns that are recognized more representative of the general public.

More than anything else, pointing to these bizarre examples of unusable or poorly designed features is a influential argument for evolution, and rapidly disarms those who might be lured by the deceiving "design argument". Coyne covers most of the classics and many examples that are not known as much as others, from whale hips and legs, to human tails, and a plethora of other features of the human body that are unwell designed, to dead genes and other rubbish in our DNA. The most imposing of all is the strange course of the left recurrent laryngeal nerve, which has a needlessly long course down going from the throat to the aorta and then back again, since it is said to have been once attached to a gill arch in the developing embryo. In chapter four, Coyne goes over all the overpowering evidence from biogeography, from the islands and their strange biotas to the peculiar forms left over from the breakup of

The data generated with the Flylab software seemed to confirm the hypothesized mode of inheritance for the phenotype of having the shaven bristles.

Patrons like myself stood in line scanning the café for empty tables and available seats. The arrangement of the tables in this area allowed for more seating flexibility and appeared to lower social boundaries between customers while encouraging interaction between members of cliques and individual patrons. Armed with my laptop and cappuccino, my observations occurred from an empty table in the center of the café.

First we started with the nasal index, which was .50, perfectly matching the results from the average asian skull. The nasal silling and prognathism also pointed towards asian, showing rounded ridges and variable respectively. However, the next two traits were both positive for female. After much time was spent checking our data, we decided to conclude that the body was asian because ⅗ measurements showed that

The purpose of this experiment is to determine the allele frequency of attached versus detached ear lobes in our society and distinguish if there is a recognizable difference between the two. This is a trait based on a single gene and is easily studied. Attached ear lobes connect directly to the side of the head, while detached ear lobes hang down below the point of attachment. One objective is to determine which earlobe is more dominant for our population.

The results show that under selection factors and environmental differences natural selection determines which allele should become more common. In the control simulation the frequency of white alleles to brown alleles, once this mutation was added, was about the same amount. It was almost half white and half brown. In simulation two the environment was an equatorial climate such as a forest and wolves were used as the predatory influence. Once the predatory factor was introduced it can be seen that the alleles of white fur decreased and at the end of the simulation the allele was almost lost. Thus, brown fur alleles were naturally selected in the equatorial environment. The fur color blends in with the environment helping them become harder to find by predators. Whereas, for the white bunnies their phenotype stood out in an equatorial environment causing them to be caught easily. Hence, it can be said that the brown fur alleles had a higher fitness which is why their occurrence was greater and that the white allele was less fit leading to less offspring being produced. Consequently, this supports my hypothesis that the brown fur allele would have a higher frequency in the equatorial environment.

Observe skull sample and record nasal root, lower border of nasal aperture, orbital shape, malar tubercle, dental shape, and lingual side of incisors. Compare your observations with the information in lab book’s (table 8.3) characteristics to determine ancestry of the

Mr. Gotcher requested Starbucks as a location to have alone time, but after further review, it was determined that the number of people at Starbucks at any given time, made it difficult to approve this reduction. Bryant has requested going to a “pawn shop”, and “game store”, as other areas he would like to patron alone as a reduction.

To determine the genotype of the members in my group and the class with regards to the TAS2R38 and LCT genes, first, DNA was extracted from epithelial cells to be used for PCR to amplify the DNA of the targeted loci. Then, restriction enzyme digestion was performed to cut the DNA into fragments in order to perform Restriction Length Polymorphism Analysis to decipher the different lengths. Differing lengths of the DNA accounts for different alleles on that specific gene, therefore determining heterozygosity and homozygosity of the genotype.

Lieberman (2001) discusses in his paper studies that have demonstrated correlations between race and brain size, with varying results. Studies were first done in the 19th century where measurements were taken of cranial capacity. In these studies, Caucasians were reported to have larger brains than other racial groups, however in recent studies; East Asians were reported as having larger brains and skulls. More common among earlier and recent studies, it was reported that Africans had smaller skulls than either Caucasians or East Asians. However criticisms have been raised against a number of these studies regarding questionable methods and racial discrimination (Lieberman, 2001).

Starbucks positions itself as a place college students can hang out, study, write term papers and meet people. A Starbucks appeal to this consumer directly through introducing technology as soon as it comes available, focusing on social networking and actively cultivating a “cool” image. The young adult audience grows 4.6 percent each year (O’ Farrell).” However, the majority of the advertising is catered to Adults around the ages of 25 to 40. Adults seem to prefer a pick me up first thing in the morning on their way to work. Most Starbucks today have a drive thru to make it faster to grab and go.
