Hereditary Unit
A hereditary unit or a gene determines a particular characteristic in an organism and can be passed on unaltered to progenitors. It is located on a specific location of a chromosome. A gene may have multiple transcription units.
Hereditary
(Science: genetics) Transferred via genes from parent to child. Tending to occur among members of a family usually by heredity; an inherited disease; familial traits; genetically transmitted features.
Hereditary Hemochromatosis Timeline
1865 - Hemochromatosis is first described by Tousseau, who cared for a diabetic patient with cirrhosis of the liver and bronzed skin pigmentation, classic symptoms of HH.
hereditary material - the information which is passed from one cellular generation to the next (encoded in DNA in humans).
Hereditary material (both DNA and RNA) is needed for a cell to be able to replicate and/or reproduce. Most organisms use DNA. Viruses and viroids sometimes employ RNA as their hereditary material.
Hereditary nonpolyposis colorectal cancer (HPCC) A common form of hereditary colon cancer due to defective correction of DNA mismatches. Also called Lynch syndrome.

This is a hereditary disease whose symptoms usually appear shortly after birth. They include faulty digestion, breathing difficulties and respiratory infections due to mucus accumulation, and excessive loss of salt in sweat.
- A unit of hereditary information. A gene is a section of a DNA molecule that specifies the production of a particular protein.
Gene amplification
- The increase, within a cell, of the number of copies of a given gene.
Genes: The hereditary material coded in cells that determine how an organism will look and behave. A gene is a single unit located on a chromosome and is thereby passed from one generation to the next.
A basic unit of hereditary material; an ordered sequence of nucleotide bases that encodes a product (this product could be just RNA like rRNA or finally coding for a protein).
Detection of hereditary diseases
The detection of hereditary diseases in a given genome is a long and difficult process, which can be shortened significantly by using PCR.
Gene -- a hereditary unit that occupies a certain position on a chromosome; a unit that has one or more specific effects on the phenotype, and can mutate to various allelic forms.

Although such disorders are inherited, they depend on the simultaneous presence of several alleles; thus the hereditary patterns are usually more complex than those of single-gene disorders. Compare single-gene disorders.

Evolution is a change in the gene pool of a population over time. A gene is a hereditary unit that can be passed on unaltered for many generations. The gene pool is the set of all genes in a species or population.
Gene: An ordered sequence of nucleotides which act as the functional subunit of hereditary information. The collection of genes in an organism determine the characteristics of that organism.
