    “Simple peck-order bullying is only the beginning of the kind of hierarchical behavior that can lead to racism, sexism, ethnocentrism, classism, and all the other 'isms' that cause so much suffering in the world.” Octavia E. Butler. Everyone needs their “place” in society: leader, hunter, builder, or even follower and securing a place in society can often lead to conflict. The need for hierarchy is evident all throughout Lord of the Flies, a novel by William Golding about a group of British boys stranded alone on an island. The boys are able to form “social classes” by the end of chapter one by establishing dominance over one another, even if they had to do it through simple peck-order bullying. The formation of social classes is one of the most important and impactful events in Lord of the Flies. The first example of an established hierarchy is when Ralph and Piggy meet. Piggy asks Ralph all these questions and invites him to answer but it takes fourteen lines of dialogue until Ralph responds to Piggy. Golding describes Ralph's behavior towards Piggy when he writes, “He tried to be offhand and not too obviously uninterested, but the fat boy hurried after him.” (8). The language in which Golding uses to describe Piggy is also somewhat demeaning. For example, Piggy is described as “fat boy” until he tells Ralph that…

    Introduction Aggressive behaviour in laying hens may be problematic, especially when behaviours such as feather pecking and cannibalism occur (Hughes, 1997). One article states that, in small flocks of laying hens, aggressive behaviour is exhibited when unfamiliar birds are present (D’Eath, 2003). Chickens tend to form dominance hierarchies, which leads to fighting to establish dominance, which may also be called a pecking order (D’Eath, 2003). In smaller flocks, once dominance has been…

    Analysis of phenotype and genotype using Phenylthiocarbamide (PTC) variation taste sensitivity Introduction Taste occurs when chemical signals stimulate taste receptor cells in the oral cavity to detect tastes such as sweet, sour, salty, bitter and umami. PTC taste sensitivity is very common substance used to study taste perception. Many studies have provided insights into tastes perception using sodium benzoate and thiourea. PTC sensitivity has often been used for practical demonstrations in…

    Originally it was believed that all traits are blended together. Due to the work of Gregor Mendel, though, it was shown that characteristics are a result of inherited factors, known as genes1. Genes are units of heredity on a chromosome that bring about our existence and create diversity. This diversity arises from the fact that there are different forms of genes known as alleles. All the alleles of an organism are referred to as that organism’s genotype and results in an organism’s phenotype,…

    “Chédiak-Higashi syndrome is an autosomal recessive immunodeficiency disorder characterized by abnormal intracellular protein transport,” (Nowicki ,“Chediak-Higashi Syndrome,” para.2). It is caused by mutations of the LYST gene which is also known as the CHS1 gene. This gene makes “a protein known as the lysosomal trafficking regulator,” (Genetics Home Reference, January 2014). They cause the lysosome to enlarge which ultimately causes problems with normal cell function. “Patients with…

    ABSTRACT In this experiment we set up crosses between mutant and wildtype flies in order to find similarities to Mendel’s work with pea plants. We did this by placing females in vials with males and waiting one week. After one week we obtained the second generation and were able to observe the different phenotypes that resulted from the cross. We were able to count each phenotype under a microscope and record the number of each type. We used this data to calculate the chi square value, which…

    To learn more about genetics, I conducted an experiment using Reebops to model how genetics is transferred from parents to offspring. At the beginning of my experiment I conducted four hypotheses, one for each of my four crosses. I had two monohybrid crosses and two dihybrid crosses. My first monohybrid cross hypothesis, was the antenna trait being studied is autosomal and undergoes independent assortment. My second monohybrid cross hypothesis, was the body segment trait being studied is…

    Discussion: My first hypothesis that the sepia eye and ebony body experimental cross would result in a 9:3:3:1 ratio, and that the traits would be autosomal, unlinked recessive, was found to be false. I chose to reject my hypothesis because my calculated test statistic, 587.5, was larger than the critical value, 7.815. The traits, ebony and sepia, are linked, seeing that they fit in 2:1:1 linkage ratio and that the recombinant number is smaller (Table 1.1). They are autosomal; the amount of…
