Gene Yang

on a small scale, within a [shared gene pool] population” (Berkeley 2006). The shared gene pool experiences genetic changes that can create differences within a species. These genetic differences are inherited from one or both parents. Genes are either lost or combined differently and can result in things such as different hair color, longer legs or bigger ears. There are four processes that contribute to microevolution: 1. Mutation – a physical change in a gene. An example of mutation is…

On Tuesday, our small groups discussed the ethical dilemmas that revolved around genetic engineering and whether or not it should be banned. This topic fascinated me since it is a new emerging technology that could greatly affect the human population. Although this technology is only in its infancy, it has lots of controversy. When I first thought about this topic I wondered why anyone wouldn’t want this technology to advance: there is the potential for unprecedented positive effects like…

in which all the traits categorized nearly overlap among the populations (Graph 4). Therefore, these graphs verified our hypothesis stated in this paper because the steep slope shows secondary contact and the interesting point tell us that there is gene flow within the hybrid zone, keys for a secondary hybrid zone. In addition, the steep on the graph, stated in the results, between populations 3, and 4 signifies the disfavor for dispersal and two species are hybridizing. There is no evidence to…

sequence affected by it should have a role in the disease. Therefore, gene level evidence is required to establish the implication. MacArthur et al. suggested that the gene level evidence which can implicate sequence variants toward complex diseases include genetic and experimental evidence. Gene burden results are genetic evidence, and experiments addressing protein interactions, biochemical function, expression of the gene, gene disruption, model systems differences, and rescue are…

are the added growth genes from the Oncorhynchus tshawytscha or more commonly known as the pacific chinook salmon, and the switch-on gene from the Zoarces americanus, or more commonly known as the ocean pout. To input these genes from the pacific chinook salmon and the ocean pout into the salmon, recombinant DNA technology is used. The scientists first identify what genes they would like to add, in this case the genes of interest are the growth gene and the switch-on gene, and isolate them.…

Background and need: During embryo development many factors can determine the future outcome and growth of developing embryo. These factors, whether genetic or environmental, will influence the cells within the embryo and could result in a lasting developmental abnormality, such as unwanted apoptosis. Ethanol, a known teratogen, is one such unorthodox environmental factor that if present will have an effect on the embryo’s development; namely defects in the cardiovascular system, structural…

1) Explain how the Lin et al. used the catFISH technique to determine which neurons are involved in particular behaviors (3 pts) Lin et al. used catFISH (cellular compartment analysis of temporal activity by fluorescent in situ hybridization) to compare the activation of c-fos expression during two successive episodes of behavior (either the same behavior or different) in the same animal. Through experimentation, researchers discovered that animals killed five minutes after fighting expressed…

elegans genes lin-11 and mec-3 were the first to be associated with the LIM homeodomain proteins. The genes lin-11 and mec-3 are important to Caenorhabditis elegans because they are involved with neuronal differentiation, these proteins correspond to the ‘L’ and ‘M’ in acronym. lin-11 specifically influences…

Genetic Traits Exhibited The earthworm possesses 36 chromosomes. Their tends to be less adaption and therefore less diversity within species as the earthworms tend to move considerably in their vast environment.The earthworm has a basic shape of a cylinder. The body of the earthworm is divided into several segments which carry bristles that are called setae. The entire body of an earthworm is surrounded by a thin mucus which increases its mobility. At the first segment of the body, the…

The doctors show that people can use lots of different ways to go wrong with personal DNA. Genome Sequenced can help people find out the mutations; However, most of the people think that Genome Sequenced are cheating them. For example, it may confuse doctors, scare patients and drive up costs. In the article, “YOU CAN GET YOUR WHOLE GENOME SEQUENCED. BUT SHOULD YOU? “(2017) MEGAN MOLTENI shows Genome Sequenced can help patients take care their body and almost no side effects. First of all,…
