Heritability

In this chapter, complex traits, or otherwise known as quantitative traits, were examined. Quantitative traits are determined numerically, as well as by different genes that are influenced by the surrounding environment. A few examples of these types of traits include, but not limited to, height, the rate of our ability to metabolize food, and the speed of a cheetah when chasing its prey. To begin, quantitative traits can be anatomical, physiological, and behavioral traits, as well as diseases.…

example of natural selection since the traits frequency changes over time. Also, it includes the 3 required characteristics of natural selection, variation, heritability, and selection. The first characteristic, variation, is present since some of the mice had light fur while some of the mice had black fur. The second characteristic, heritability, is present since the mice with dark fur often had offspring that had dark fur. The last characteristic, selection, is present since the mice with…

study, the Minnesota Study of Twins Reared Apart (MISTRA), Bouchard, Lykken, McGue, Segal, and Tellegen (1990) studied more than 80 sets of MZ and DZ twins who were separated as infants and raised in separate environments in order to determine the heritability of psychological traits, including intelligence. The participants completed approximately 50 hours of assessment, including personality and occupational interest inventories, mental ability batteries, an IQ test, and interviews about life…

differ in size and in diverse habitats and may have originated from the same finch ancestor that arrived from the mainland about two million years ago. The three factors for evolutionary process, variability, selection by differential fitness, and heritability, are key to tracking the “micro-evolution” of the Galapagos finches and to further understanding about how diverse environments contribute to the creation of new species.…

In his excerpt for The Examiner “Why Boys Become Vicious”, award winning author Sir William Golding implies that people's reasons for evil, regardless of whether they were born with cruelty or their situation brought it out, is greatly affected by their home environment, social situation, fear, and chaos. This stand ties into one of the oldest debates in the history of psychology is the Nature vs Nurture which centers around whether a person's development is predisposed in his DNA, or a majority…

factually incorrect gauge. They went on to view intelligence as a modifiable agent where test scores would represent a starting line rather than an ending. This however was also seen as incorrect due to disappointing results. There was an argument for heritability playing a role in cognitive abilities but this was seen as a false assumption due to there being no conclusive data that supported the notion that intelligence was another trait that could be passed down. The authors of the book came…

In the HBO documentary video, Dr. Mark Willenbring, the former Director of Treatment and Recovery Research at the National Institute on Alcohol Abuse and Alcoholism, discusses many concepts related to alcohol use disorder. First, he identifies the components that play an important role in the development of addiction. Next, he describes the options that are available to treat alcohol dependence and what are the characteristics of an effective therapy. In the last part of the video, Dr.…

A very widely debated scientific dilemma that has been going on for years is whether or not viruses are alive. Although viruses do have a few characteristics of life, they do not have all of them, and they especially don’t have the most important ones. Throughout the case study there were great arguments for either side, and although it was a tough decision, I do not believe that viruses are alive. Viruses cannot metabolize energy and they are not made up of cells. One characteristic of life is…

Depression doesn’t represent only one gender or race but towards a whole category of human beings from men to women to kids to adults. Depression is more than just feeling sad and it is more than just a chemical imbalance. In the earlier era of time when depression was just coming into light depression was thought to be a chemic al imbalance in the brain that can simply be cured with medication. But actually, it is caused by a combination of biological, psychological, and social factors.…

Cortni Volkman AGR 315 Equine Osteochondrosis Exercise intolerance in equines is defined as a . One intolerance often seen in younger, performance prospect horses is the development of osteochondrosis lesions and osteochondrosis dissecans. There are a wide variety of theories to what exactly causes the development of these lesions but observably osteochondrosis is endochondral tissue that has failed to properly ossify thus creating abnormal cartilage on the bone, often seen in joints.
