genetic

 [jĕ-net´ik]
1. pertaining to reproduction or to birth or origin.
2. inherited.
genetic code the arrangement of nucleotides in the polynucleotide chain of a chromosome; it governs the transmission of genetic information to proteins, i.e., determines the sequence of amino acids in the polypeptide chain making up each protein synthesized by the cell. Genetic information is coded in DNA by means of four bases: two purines (adenine and guanine) and two pyrimidines (thymine and cystosine). Each adjacent sequence of three bases (a codon) determines the insertion of a specific amino acid. In RNA, uracil replaces thymine.
genetic map
1. the location of mutations along the length of a chromosome, as determined by recombination experiments. The unit of length is the centimorgan (cM), one crossover per meiosis.
2. the sequence of base pairs along the DNA of a chromosome, a technique being applied to humans.
A gene map of Chromosome 18. From Copstead, 1996.
genetic marker a gene having alleles that are all expressed in the phenotype, that is, they are codominant, and which can be used to study inheritance. The various blood group systems and serum or red blood cell proteins easily detected by electrophoresis or immunodiffusion are commonly used markers.

Genetic

The term refers to genes, the basic units of biological heredity, which are contained on the chromosomes, and contain chemical instructions which direct the development and functioning of an individual.

genetic

1. pertaining to reproduction or to birth or origin.
2. inherited.

genetic abnormality
inherited defect, which may or may not be congenital.
genetic analysis
analysis of breeding and pedigree records to establish degrees of relationship between single animals and groups of animals. Segregation analysis with full-sibling families is an obvious technique.
genetic code
the manner in which the arrangement of nucleotides in the polynucleotide chain of a chromosome governs the transmission of genetic information to proteins, i.e. determines the sequence of amino acids in the polypeptide chain making up each protein synthesized by the cell. Genetic information is coded in DNA by means of four bases (two purines: adenine and guanine; and two pyrimidines: thymine and cystosine). Each adjacent sequence of three bases (a codon) determines which of the 20 amino acids will be inserted into the nascent polypeptide.
genetic complementation
genetic control of inherited disease
consists of preventing carrier animals from contributing their genes to succeeding generations of the population of which they are members.
genetic correlation
a change in an unselected character resulting from selection of another character during a breeding program.
genetic defects
defects of function or structure passed on from parents to offspring. Inherited defects.
genetic determination
see broad-sense heritability.
genetic disease resistance
inherited resistance to diseases caused by non-hereditary risk factors.
genetic dominance
see dominance (2).
genetic drift
see antigenic drift.
genetic engineering
the manipulation of genes by recombinant DNA technologies to produce chromosomal combinations that are unlikely to occur by natural means, for example the introduction of genes for insulin into a yeast cell which then produces insulin which can be purified and used as a therapeutic substance. See also recombinant DNA technology.
genetic etiology
disease caused by inheritance of specific disease without the intervention of other risk factors; established by strongly positive relationship in terms of genes held in common between the affected patient and other affected individuals.
genetic evaluation
assessment, for predictive purposes, of productive improvement or conformational characteristics, of the gain to be derived by the use of the animal in question in a breeding program.
genetic expressivity
genetic heterogeneity
demonstrated by the way in which more than one disease with identical clinical signs can be inherited.
genetic immunization
use of a cloned genetically engineered gene with an encoded antigen to immunize the host against that antigen. See also DNA vaccine.
genetic map
the linear arrangement of genes along a chromosome. Called also linkage map.
genetic merit
inherited productivity or performance qualities.
mobile genetic elements
see transposable genetic elements (below).
genetic penetrance
genetic production potential
inherited productivity but still influenced by environmental risk factors.
genetic resistance
genetically determined resistance to specified infectious agents.
genetic selection
selection of animals as breeding stock on the basis of known inherited characteristics.
transposable genetic elements
pieces of DNA varying in length from a few hundred to tens of thousands of base pairs found in both prokaryotic and eukaryotic cells that move from place to place in the chromosomes of a single cell; some are viruses. Called also mobile genetic elements or transposons.
genetic variance
that portion of the phenotypic variance of a trait in a population which can be attributed to genetic difference amongst individuals.

Patient discussion about genetic

Q. Are there genetic factors involving allergies? 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.
