genetics [jĕ-net´iks] the branch of biology dealing with the phenomena of heredity and the laws governing it.biochemical genetics the study of the fundamental relationships between genes, protein, and metabolism. This involves the study of the cause of many specific heritable diseases. These include those resulting from the improper synthesis of hemoglobins and protein, such as sickle cell disease and thalassemia, both of which are hereditary anemias; some 200 inborn errors of metabolism, such as phenylketonuria and galactosemia, in which lack or alteration of a specific enzyme prohibits proper metabolism of carbohydrates, proteins, or fats and thus produces pathologic symptoms; and genetically determined variations in response to certain drugs, for example, isoniazid.clinical genetics the study of the causes and inheritance of genetic disorders. In addition to the diseases mentioned under biochemical genetics, other aspects of clinical genetics include the study of chromosomal aberrations, such as those that cause mental retardation and down syndrome, and immunogenetics, or the genetic aspects of the immune response and the transmission of genetic factors from generation to generation.
Many pediatric hospital admissions involve genetic disorders. In obstetrics and neonatal medicine, prenatal diagnosis of genetic defects and improvement of pre- and perinatal conditions are a major concern. In adults, such diseases as breast cancer, coronary artery disease, hypertension, and diabetes mellitus have all been found to have predisposing genetic components that are relevant to identification of risk factors and early diagnosis.ge·net·ics (jĕ-net'iks), 1.

The branch of science concerned with the means and consequences of transmission and generation of the components of biologic inheritance. 2. The genetic features and constitution of any single organism or set of organisms. [G. genesis, origin or production]genetics The branch of biology concerned with the structure, location, abnormalities and effects of the GENES. Medical genetics is mainly concerned with the expression of abnormal genes or gene combinations in the production of disease. Knowledge of such matters allows useful GENETIC COUNSELLING. William Bateson, (1861–1926) was the English physiologist whose studies and publications led to his being known as the ‘father of genetics’. Curiously, Bateson persistently opposed the chromosome theory of heredity.genetics the science that investigates patterns of inheritance between generations, together with how genes express themselves within the lifetime of individual organisms.GeneticsThe study of hereditary traits passed on through the genes.Mentioned in: Gene Therapyge·net·ics (jĕ-net'iks) 1.

My entire family suffers from different allergies. It is clear that there is a connection, is that true?A. The risk of allergic sensitization and the development of allergies varies with age, with young children most at risk. It is known that there is a strong genetic relation and allergies are usually common among family members. Ethnicity may play a role in some allergies, however racial factors have been difficult to separate from environmental influences and changes due to migration. Q. Is celiac genetic? I have one son with celiac disease from my first marriage and me second wife is now pregnant,I was wondering what are the chances for this soon to be born daughter of mine to have celiac as well- if I maybe carry the genetic flaw and is there a way to find out?A. Celiac disease is a very common illness (about 1 in a 100 people suffer from it in different levels), and it is known to have a strong genetic connection. However, there is not one specific mutation that you can get genetic testing to see if you are carrying it. Your soon to be born daughter will have a higher chance than the regular population to suffer from the disease, but it does not necessarily mean she will. Q. is Bipolar genetic? A. Bipolar disorder has a very strong genetic background: The approximate lifetime risk of this disease in relatives of a bipolar patient is 40 to 70 percent for a monozygotic (identical) twin and 5 to 10 percent for a first degree relative, compared with 0.5 to 1.5 percent for an unrelated person.
