Genetic Testing
Genetic testing has provided important clues to understanding our health, but it has also raised many ethical, legal, and medical questions and concerns.This book explores the breadth of genetic testing, its possibilities, and the controversies that surround its use. The mapping of the human genome has paved the way for a variety of genetic tests.Expectant mothers can have their fetus screened for a variety of genetic abnormalities, and couples worried that they might be carriers for a genetic disorder can be tested before deciding to have children.Women can be screened for the BRCA2 gene that has been linked to increased risk of breast cancer.Individuals curious about their ancestry can find out more about their heritage.Genetic testing can also be used to establish paternity and help solve crimes. Part of Greenwood's Health and Medical Issues Today series, this book is divided into three sections.Part I explores the history of genetic testing, including the rise of direct-to-consumer tests, and outlines the current applications and contexts in which genetic testing is performed.Part II delves deep into the ethical, legal, financial, medical, and psychological issues and controversies that surround genetic testing.Part III provides a variety of useful materials, including case studies, a timeline of critical events, and a directory of resources.

Creating Future People : The Science and Ethics of Genetic Enhancement
Creating Future People offers readers a fast-paced primer on how advances in genetics will enable parents to influence the traits of their children, including their children’s intelligence, moral capacities, physical appearance, and immune system.It explains the science of gene editing and embryo selection and motivates the moral questions it raises by thinking about the strategic aspects of parental choice.Professor Anomaly takes seriously the diversity of preferences parents have, and the limits policymakers face in regulating what will soon be a global market for reproductive technology.Anomaly argues that once embryo selection for complex traits happens it will change the moral landscape by altering the incentives each person faces.All of us will take an interest in the traits everyone else selects, and this will present coordination problems that previous writers on genetic enhancement have failed to consider.Anomaly ends by considering how genetic engineering will transform humanity. Key Updates to the Second EditionSignificant revisions to include more details about what will be scientifically possible in the coming years and the moral issues these developments will raise. New and substantial coverage of embryo selection (guided by polygenic scores) for minimizing the risk of genetic diseases. Engagement with all important, new publications on the science of genetic enhancement

What does genetic drift mean in evolution?
Genetic drift is a mechanism of evolution that refers to the random changes in allele frequencies within a population. These changes occur due to chance events, such as natural disasters or the random mating of individuals. Genetic drift can lead to the loss of genetic variation in a population, which can have significant impacts on the evolutionary trajectory of a species. Over time, genetic drift can result in the fixation of certain alleles in a population, leading to genetic differentiation and potentially the formation of new species.

How does genetic modification of genetic information work?
Genetic modification involves altering the genetic information of an organism by introducing new DNA into its genome. This can be achieved through various techniques such as gene editing using tools like CRISPR, or by introducing foreign DNA into the organism through a process called transgenesis. The new DNA can be designed to add, delete, or modify specific genes, which can result in changes to the organism's traits or characteristics. Genetic modification has the potential to create organisms with improved traits, such as increased resistance to diseases or improved nutritional content.

What is the difference between genetic and genetic engineering?
Genetics refers to the study of genes, heredity, and variation in living organisms. It involves understanding how traits are passed down from one generation to the next. On the other hand, genetic engineering is the deliberate modification of an organism's genetic material using biotechnology. This can involve altering specific genes to achieve desired traits or characteristics. In essence, genetics is the study of natural genetic processes, while genetic engineering involves the intentional manipulation of genetic material for specific purposes.

What genetic orientation?
Genetic orientation refers to the specific genetic makeup or characteristics of an individual, which can influence various traits and predispositions. This orientation is determined by the combination of genes inherited from one's parents and can impact things like physical appearance, health conditions, and even personality traits. Understanding one's genetic orientation can provide insights into potential health risks and help in making informed decisions about lifestyle choices and medical care.

Genetic Ethics : An Introduction
Colin Farrelly contemplates the various ethical and social quandaries raised by the genetic revolution.Recent biomedical advances such as genetic screening, gene therapy and genome editing might be used to promote equality of opportunity, reproductive freedom, healthy aging, and the prevention and treatment of disease.But these technologies also raise a host of ethical questions: Is the idea of “genetically engineering” humans a morally objectionable form of eugenics?Should parents undergoing IVF be permitted to screen embryos for the sex of their offspring?Would it be ethical to alter the rate at which humans age, greatly increasing longevity at a time when the human population is already at potentially unsustainable levels?Farrelly applies an original virtue ethics framework to assess these and other challenges posed by the genetic revolution.Chapters discuss virtue ethics in relation to eugenics, infectious and chronic disease, evolutionary biology, epigenetics, happiness, reproductive freedom and longevity.This fresh approach creates a roadmap for thinking ethically about technological progress that will be of practical use to ethicists and scientists for years to come.Accessible in tone and compellingly argued, this book is an ideal introduction for students of bioethics, applied ethics, biomedical sciences, and related courses in philosophy and life sciences.

What is the difference between genetic research and genetic engineering?
Genetic research involves studying genes and their functions to understand how they contribute to traits and diseases. It focuses on identifying genetic variations and their impact on individuals. On the other hand, genetic engineering involves manipulating genes to create new traits or modify existing ones. It is a technology that allows scientists to directly alter the genetic makeup of an organism. In essence, genetic research is about studying genes, while genetic engineering is about actively changing them.

How does the genetic modification of the genetic information work?
Genetic modification involves altering the genetic information of an organism by introducing specific changes to its DNA. This can be done by inserting new genes, removing existing genes, or modifying the expression of certain genes. Techniques such as CRISPR-Cas9 allow for precise editing of DNA sequences, enabling scientists to target specific genes and make desired modifications. Once the genetic information has been modified, the organism's cells will start producing proteins based on the new instructions encoded in its DNA.

What determines how much genetic mutations affect, what we also call evolution?
The impact of genetic mutations on evolution is determined by several factors. Firstly, the type of mutation and its location within the genome can influence its effect on the organism. For example, a mutation in a gene that codes for a critical protein may have a more significant impact than a mutation in a non-coding region. Additionally, the environment in which the organism lives can also play a role in determining the impact of genetic mutations. Certain mutations may be advantageous in one environment but detrimental in another. Finally, the frequency of the mutation within a population and the process of natural selection will also influence the extent to which genetic mutations affect evolution.
