(redirected from genetical)
Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.


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.

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.
