This lab was very effective for experiencing the breeding of traits in a realistic simulation and correlating these visual presentations into the Punnett Squares. The objective of this lab was to notice and explore the key differences between genotype and phenotype. Where phenotype is the physical characteristics of a trait, and genotypes are all the possible genetic combinations an organism can obtain from its parental generation. Two mice were used in this experiment, and these two mice were…

Aceruloplasminemia We learned about many What is it? Explain/describe the general symptoms of your choice. Best described as iron accumulation in the body, aceruloplasminemia is a genetic disorder where iron accumulates in organs. This bc of such, it is classifed as a neiodgentiv disirder Symptoms typically manifest during adulthood approximaentl y 85% of synomatic patients are also diagnosded with anemia, 80% with diabetes, 77% with reRetinal degeneration, and Neurologic symptoms…

Kittens from the same litter can look different for a multitude of reasons. The reason each kitten looks different is contained in the genes of each kitten. The genes are located inside the kitten’s 38 chromosomes. Half of the kitten’s chromosomes are inherited from his or her mother, while the other 19 are inherited from his or her father. DNA is tightly coiled inside of each chromosome, and the chromosomes contain genes which are comprised of proteins and nucleic acids, specifically Adenine…

Olivia Olson Dr. Alex Hill Bio A 348 9 December 2016 Tay-Sachs: Why so Selective? There are aspects of nature that puzzle the world. Scientists, as curious as they are, try to figure out and solve nature’s great mysteries. One biological phenomenon that appears is Tay-Sachs disease. This is a disorder that tends to appear in only a handful of populations around the world. For quite sometime it was a mystery as to why this deadly disease tended to only show up in certain populations; but thanks…

the authors found that misdiagnosed dizygotic twins demonstrated remarkable similarity in physicality and weight even exceeding that of true monozygotic twins. Song et al., (2010) suggests that a parsimonious questionnaire used in diagnosing the zygosity of the infant twins would be advantageous, whereas, adding physical or physiological measures would either confound the correct diagnosis or diminish the effectiveness of the study in comparison to using questionnaire alone or through…

As the population of multiple births continues to rise, inquiring minds continue to expand the depth of knowledge available. Tully et al. (2004), start to explore the results of separating twins, and no longer focus on why they are being separated in the classroom. Although this study was conducted in the United Kingdom, the data are still applicable to schools in the United States. In reviewing the current research to complete the study, Tully et al. discovered current “decisions about…

differences in IQ, personality, psychopathology, and the amount or impulsiveness and risk-taking propensity, respectively. Each twin was also given zygosity testing to confirm that they were in fact monozygotic twins. They were each given epigenetic testing as well, focusing on DNA methylation. On the IQ test both twins scores were nearly identical and the zygosity test confirmed that they were indeed monozygotic twins. The rest of the tests showed the twins to be remarkably different. The…

The article ‘Sources of Human Psychological Differences: The Minnesota study of Twins Reared Apart’ includes the studies of Bouchard, Lykken, McGue, Segal and Tellegen which reveals psychological differences between monozygotic twins who were nourished separately and together. This study is derived from the Minnesota study which has conducted research over monozygotic and dizygotic twins from around the world since 1979 (Bouchard, Lykken, McGue, Segal, Tellegen, 1990). The monozygotic twins are…

The purpose of this study is to demonstrate if success in academics or life can be predicted by a person’s degree of grit. The authors of this paper define grit as perseverance and passion for long-term goals as defined by Duckworth of University of Pennsylvania. At the time of this research there seems to be a lot of hype around grit since the department of education in the US and UK have been focusing on increasing student’s grit. Somewhere in the articles it states that previous research has…

The basic benefit of the artificial meta-analysis over the literature review is the possibility of producing a less partial measurable analysis of the conclusions of numerous major experimental studies. In regards to this specific experiment, the researchers attempted to use those principles that are primarily used for larger literature works. There was heavy usage of MEDLINE searches that were used to facilitate this article. In order to recognize all pertinent primary studies, computerized…
