A plethora of internal and external variables combine to create individual personalities, behaviors and psychopathologies supposedly unique to every human being. The argument of genetic makeup versus environmental influences, however, has researchers working to determine what really shapes us. Some say genotypes control how people think, feel and behave. Others believe it is the environment alone that is responsible for molding humans into who they are. There is much unknown in this field, but…

Viruses are infective agents that are unable to support themselves and rely on other hosts for survival. Although they are not a living thing, viruses are able to infect humans, plants, bacterias etc. Depending on the type of virus, they target a specific organ or type of cells and inject their DNA or RNA in the cell to reorganize the genetic material of the cell. The cell then follows the new DNA instruction and produces more viral viruses. The adenoviridae, better known as adenoviruses, are a…

or insufficient enough, from birth restricts a person to a career not requiring an education, such as a cleaner. Creation of a new form of prejudice produces the idea of having greater or second-rate genes. The character, Vincent Freeman, contests his fate of being an “invalid” by purchasing the gene identity of Jerome Morrow, who has been genetically engineered to be “valid”. This movie can be viewed in different ways. A ‘perfectionist’s’ type of person may see this…

Trisomy is a cell that has three copies of one chromosome instead of having the normal two copies. Trisomy 21 is known as the congenital disorder Down syndrome. This occurs when each cell has three copies of chromosome twenty one rather than having a pair. Commonly, Down syndrome is caused by nondisjunction. Nondisjunction is "an error in which homologous chromosomes or sister chromatids fail to separate normally during meiosis or mitosis" (Huether,McCance pp.42). Scientists have discovered…

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…

Title: Exploring the Factors Affecting Post-Wound Hair Regeneration in Mice. Hypothesis: We hypothesize that in mice large wound size increases the number of hair follicle because large wound will activate the Wnt pathway that is necessary for hair follicle regeneration in wounds. Independent variables being tested: The wound size of the mice. Dependent variables being tested: The number of hair follicle. Experimental Design: This experiment will be designed to determine if large wound size,…

This is because the targeted polymorphisms are more frequently found in Caucasians and African Americans. There might be other polymorphisms for the same gene that are more frequent in the people of Asian descent. - Another limitation is that since we are only testing for targeted polymorphisms, we cannot capture all the genetic variation for that gene in the…

He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next. Mendel’s Laws of Heredity stated that each inherited trait is defined by a gene pair, genes for different traits are sorted separately so that the inheritance…

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…
