    In some populations, alleles can be lost due to random events. Genetic drift reduces allele frequencies in smaller population, therefore, decrease genetic variation. It can eliminate alleles at a faster rate in smaller population until they become fixed in the population. On the other hand, alleles in a large population rarely become fixed by genetic drift. This indicates that genetic drift has a greater effect on a smaller population by getting rid of alleles at a faster rate. Genetic variation…

    “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…

    2.RELATED WORK The artificial bee colony (ABC), an optimization technique is based upon the intelligent moving behavior of honey bee swarm was proposed by Karaboga in 2005. This kind of new Meta heuristic is inspired by the clever foraging behavior of honey bee swarm. The criteria presented in the work is for numerical function optimization. The advantage of ABC is that the global search ability in the algorithm is implemented by introducing neighborhood source production mechanism. Rao et al.…

    Usher Syndrome is a most common condition that affects both hearing and vision. A Syndrome is a disease or disorder that has more than one feature of symptom. The major symptom of Usher Syndrome is hearing lose an eye disorder called retinitis pigmentosa, or RP. RP causes night blindness and a loss of peripheral vision through the progressive degeneration of the retina. The retina is a light-sensitive tissue at the back of the eye and is crucial for vision. As RP progresses, the field of vision…

    A genetic disorder is a problem caused by one or more abnormalities in a human body . The disorders are rare , but they are possibly handed down from the parents’ genes , or maybe new mutations . One example of a genetic disorder is Tay Sachs disease . Another example of a disorder is polycystic kidney disease . What Does Genetic Testing Tell You Genetic testing gives you an idea if you’re at risk of a certain disease or not . If two parents both have a disease then the child will have a 25%…

    Spinal Muscular Atrophy Have you ever had a dream where you thought you couldn’t move? You are telling your arms to move and your legs to move but they don’t seem to understand. You are screaming inside because now you are scared because you don’t know what to do. Your body is stiff and not moving. You just keep trying and trying but still can’t move.

    When dog owners identify an interesting trait in a dog, Some owners would breed that in hope that the trait would be passed on. After many times of this situation happening, (especially where two dogs with the same trait are bred with each other) traits become fixed. If you can understand the genetics, you can start to predict on what you will see in a crossbreed. As of now there are over four hundred breeds of dogs and all are maintained as pure-bred stocks through selective breeding, which…

    Genetics is a fundamental part of life as it is related to how we receive and develop traits from our parents and what could be given to our children. The concept of genetics was started around 1856 by Gregor Mendel who conducted experiments with pea plants and established many of the rules of heredity now used in modern genetics. According to Corcos and Monaghan (1984) Mendel did not consider the two laws written by him to be laws at all but to be assumptions or a hypothesis that were later…

    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…

    Introduction: Hardy Weinberg theory was an effective tool for recognizing the different genotypes from one generation to the next and each allele frequency. This theory notifies us by how Mendelian inheritance was the lead for all genetic variation and it can be used to follow Mendelian’s rules of segregation and the combination of alleles. Polymerase chain reaction was one of the essentials that is used in the Hardy Weinberg theory of genetic equilibrium which was used in determining the…
