Literature Review

Abstract
Why
The genetic basis of dog coat growth pattern, length, and curl is not as well-characterized as coat color.
What/How
Genome-wide association studies (GWAS) were performed on >1000 domestic dogs from 108 breeds to determine which genes direct or influence dog fur phenotypes.

Major Results

Distinct mutations in three genes (RSPO2, FGF5, and KRT71) were identified to have combinatorial effects on coat phenotypes in purebred dogs in the US.

Concise

The abstract contained all necessary information without being lengthy. Scientific jargon was kept to a minimum: enough to be understood by readers with sufficient knowledge on the topic but without Continue reading...

Biology

Biological Exemplars of Natural Selection
Ordinary, or gray wolf - Canis lupus - occupies the most extensive natural habitat of all mammals except humans. In the past, wolves inhabited most of North America and Eurasia, but now many of the gray wolf populations remained only small groups, the existence of many of which are not confirmed. The current situation is much more complicated than a thousand years ago, due to the efforts of anthropogenic influences on the distribution of predator and increased possible pressure on its population. Although in perspective wolf areal will be largely determined by human activity, Continue reading...

Questions

Paper 1 to 4
1. Briefly define the following (i.e., is it a receptor? If so what type of receptor? etc.) And provide a one sentence description of the biological function or role in the study.
a. AhR. AhR is aryl hydrocarbon receptor that is involved in hyperlipidemia (Wu 1260). It is also involved in environmental chemical-induced organ toxicity (Sherr 1245).
b. ApoE-/-. It is apoliprotein. ApoE-/- mice are found to have increased chances of developing ischemic heart diseases as a result of exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and AhR activation (Wu 1260).
c. CH223191. It is Continue reading...

Epidemiological Rationale for the Topic
The health of a person and the environment that they live in are two closely related subjects. According to Healthy people.gov (2015) the environment is a vital determinant of the life expectancy and the overall quality of life of a person. The air that people breathe the buildings they live in and the technology and machines that they use can adversely affect the length and quality of their lives. According to WHO (2015) Environmental Health can be better described in terms of the hazardous materials in the environment, natural and technological disasters, physical hazards, Continue reading...
