HUMAN GENETICS

Human Genetics is the study of inheritance as it involves in human beings. It encompasses a variety of overlapping fields including: classical genetics, cytogenetic, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, genetic counselling and clinical genetics. Genes can be the usual factor of the qualities of most human-inherited traits. Information of human genetics can be useful as it can answer questions about human nature, understand the diseases and development of effective disease treatment, and understand the genetics of human life. This article explains only basic features of human genetics; for the genetics of disorders. Medical genetics is the main branch of medicine that includes the diagnosis and management of hereditary disorders. It varies from human genetics in that human genetics is a field of scientific research that may or may not apply to medicine, while medical genetics refers to the appeal of genetics to medical care. For example, research on the inheritance and causes of genetic disorders would be a review within both human genetics and medical genetics, while the diagnosis, counselling and management people with genetic disorders could be considered part of medical genetics. Population genetics is the main of evolutionary biology responsible for investigating processes that cause changes in allele and genotype frequencies in populations based upon Mendelian inheritance. The main four different forces can influence the frequencies: natural selection, mutation, gene flow (migration), and genetic drift. A population can be verifying as a group of interbreeding individuals and their offspring. For human genetics, the populations will be composed only of the human species. The Hardy-Weinberg principle is a widely used principle to explain allelic and genotype frequencies.

In the future, scientists and Doctors hope to use our genetic information to diagnose, treat, prevent and cure many illnesses. Genes are instructions, which convey your body how to make all the proteins it needs to survive and grow. DNA sequencing is mainly used to directly examine the genomic DNA sequence of a particular gene. It methylation analysis is used to diagnose fixed genetic disorders that are caused by disruptions of epigenetic mechanisms such as genomic imprinting and uniparental disomy. Genetic tests are used to diagnose determined disorders (for example, hemochromatosis and chromosome disorders such as Down syndrome and Turner syndrome). Genetics is also increasing the capacity to predict what disorders a person is likely to develop. They are established in almost every cell’s nucleus and are made from strands of DNA (deoxyribonucleic acid). Segments of DNA are called “genes” and the ingredients. Each and every gene adds a specific protein to the recipe. Proteins construct, regulate and maintain your body.

ROLE OF GENETICS

Genetics is the study of heredity and it is a biological process where a parent passes certain genes onto their children or offspring. Although every child inherits genes from both of their biological parents and these genes in turn express specific traits and genes are made up of DNA. Some genes perform as instructions to make molecules called proteins. However, some genes do not code for proteins. Every gene compiles a specific position on a chromosome. Because genes provide instructions for making proteins and proteins determine the structure and function of each cell in the body, it orders that genes are responsible for all the characteristics you inherit.

Genetics The Future is Yours

Genetic processes work in combination with an organism’s environment and experiences to influence behaviour and development, often it referred to as nature versus nurture. Bringing you the latest in health testing and the ultimate in predictive, preventative, personalised and health care. A simple saliva test gives you more information on your genetics that can help you make better choices in your diet and lifestyle. So you make the most of your health.

Did you know that dietary factors can affect the process of your genes are expressed? Have you ever wondered why some people can control on a less than optimal diet while others are more sensitive? The answer is in your genes! DNA testing provides comprehensive information about your individual genetic profile. DNA testing explores the genes that influence your biological pathways and how that may have an influence on your health over the course of your lifetime.
