Genetics and Criminality - There have been and still are many debates about how a person’s genotype can be a significant factor in the development of your personality, but more relating to criminality. It is very hard to say that your genetic make-up is not a factor in who you become as a person, but I fully believe that the environment also is a factor as well. Having a genetic predisposition does not mean that you are automatically going to inherit whatever trait that was passed down from your parents. Everyone has a choice in who they become as individuals; it all just depends on the environment that you are raised in and the people that are around you when you are growing up....   [tags: Genetics]

The Importance of Mendel’s Laws in Modern Genetics - The Importance of Mendel’s Laws in Modern Genetics - Human genome is like an intricate library that stores vast volumes of life information. The preservation and passage of genetic books to future generation is one of the primary tasks of human genome. In the late 19th century not too long after the library of Congress was built in the United States, Gregor Mendel, an Austrian teacher and abbot, made a keen observation in the garden of a monastery at Brno. After testing and breeding 28,000 pea plants, Mendel discovered the mathematic pattern of describing how parents pass on their traits to the offspring....   [tags: Genetics]

Human-Chimpanzee Divergent Genetics - Being human, we possess a quality that is unlikely to be found in other known organisms. Since perhaps the dawn of existence, the human psyche has strived to explain the origins of this quality and what it reveals about man’s conception. The ancient Greeks surmised that the Titan god Prometheus sculpted humans in the image of the gods from the mud of the earth. The ancient Egyptians posited that humans came into being from their sun god Ra’s tears. Now in modern times, scientists believe the key to our origins lies within our closest relative, Pan troglodytes, commonly known as the chimpanzee....   [tags: Genetics]

Genetics - ... After formation along the RNA strand, the protein is and is then released. The sequence of amino acids in the protein determines its function, such as an enzyme, antibody, hormone, or structural molecule. Mutations in DNA can occur through several mechanisms. Nucleotides can be deleted from or added to the sequence, or they can be in the incorrect order. These mutations can either be hereditary or through environmental factors resulting in DNA damage. B.

This power is analytical, in such cases as the Human Genome Project, which will hopefully succeed in mapping out the genetic code for the entire human genetic composition. Moreover, this power is preventative and participatory in that it can be, and is being, used to control the behavior of humans and other animals. This new power, in the eyes of many, is as risky and potentially hazardous as atomic energy: it must be treated carefully, used under close supervision, performed under professional consent and observation, otherwise, people will begin to see this new genetic power as a dangerous drawback, rather than an advancement of human culture....   [tags: essays research papers fc]

Human cloning should not be performed by any means because it is highly likely it will create living beings not as they are intended to be produced. Rather, the results will be living beings which were created in an unnatural, man-directed way created by human choice. By acting this way, cloning gives people the power to play God. Human cloning generally has three main categories: therapeutic cloning, reproductive cloning and replacement cloning ("Cloning Fact Sheet)....   [tags: Genetics]

Critique of Data Analysis - This paper addresses a currently relevant topic of detection of associations of copy number polymorphism with traits and will be of interest to readers of Genetics Research. The simulation study showed that the additional information of CNP could increase the accuracy of predicted genotypic value, compared to using SNP information alone in an association study. The accuracy was heavily dependent on the heritability of CNP phenotypes (correlation of CNP genotype and phenotype) (Table 3). The higher accuracy of the prediction with CNP information might also result in smaller mean squared errors of prediction (Table 4)’....   [tags: Genetics] 1281 words

To What Extent is Gender Determined by Gonosomes? - Introduction Focus question: To what extent is gender determined by gonosomes. I researched what factors contribute to determine gender in humans, and specifically how much gender is specified by the sex chromosomes. In addition to this, I also looked at what the effect on gender is if someone has a gonadal, gonosomal or hormonal disorder or abnormality, and to what degree gender is influenced by what an individual identifies as. I had wanted to study a topic that had a clear scientific basis, that would be possible to find appropriate sources about and that both the scientific community and non-science writers would have varying opinions on....   [tags: Genetics]

The Pros and Cons of Genetic Screening - The goal of genetic screening is to provide information for parents who have a high risk of having a child with a disability. These parents make decisions on issues, which include the management of genetic illnesses, conditions and procedures for conception and pregnancy termination. Genetic screening in terms of discovering that a woman is carrying a baby with a disability and the women has an option of carrying the pregnancy to term or terminating it, would bring up the issue of abortion. However, the issue is not terminating a pregnancy, the issue is, should these types of information be given to parents knowing that there is good chance the end result would be to have an abortion....   [tags: Genetics] 964 words

IVF and Preimplantation Genetic Diagnosis: - In America alone there are 6.1 million couples coping with infertility (ASRM). In vitro fertilization (IVF) is one of the many assisted reproductive technologies used to help infertile couples achieve pregnancy. Since IVF is costly (the average cost is $12, 400. for one cycle), time consuming and a very emotional situation, many couples have a limited amount of opportunities to commit to the procedure and every step should be taken to maximize the chances of a successful healthy pregnancy. Preimplantation genetic diagnosis, or PGD, is a valuable tool for infertility treatment technology and can facilitate in successful IVF cycles....   [tags: Genetics] 1038 words

The Never-ending Story: Sexual Orientation and Genetics - The Never-ending Story: Sexual Orientation and Genetics It is my observation that the average person gains insight into the nature vs. nurture debate when some particular human trait that is politically or socially volatile at the time is announced as having a specific genetic origin. This observation was confirmed when, in surfing the web, I came across an article entitled, "Female Inner Ear Comes Out of the Closet (1)." While reporting on a study published by a UT psychology professor who found that homosexual women exhibit tones in the inner ear similar to those of male test subjects, the Daily Texan journalist, with no explanation or sources, effortlessly mixes and confuses the social construction with the "science" of sexual orientation—even in her or his title....   [tags: Biology Essays Research Papers]

A Flexible Gene-Based Test for Genome-Wide Association Studies - Gene-based tests for association are increasingly being seen as a useful complement to genome-wide association studies (GWAS) [1]. A gene-based approach considers association between a trait and all markers (usually SNPs) within a gene rather than each marker individually. Depending on the underlying genetic architecture, gene-based approaches can be more powerful than traditional individual-SNP based GWAS. For example, if a gene contains more than one causative variant, then several SNPs within that gene may show marginal levels of significance that are often indistinguishable from random noise in the initial GWAS results....   [tags: Genetics] 2003 words
