  Heredity - Wikipedia, the free encyclopedia
Heredity (the adjective is hereditary) is the transfer of characteristics from parent to offspring, either through their genes or through the social institution called inheritance (for example, a title of nobility is passed from individual to individual according to relevant customs and/or laws).
Charles Darwin proposed a theory of evolution in 1859 and one of its major problems was a lack of coherent hereditary mechanism.
Darwin's initial model of hereditary was adopted by, and then heavily modified by, his cousin Francis Galton, who laid the framework for the biometric school of heredity.

 Hereditary peer - Wikipedia, the free encyclopedia
Hereditary peers hold titles that may be inherited; even peers who were granted, rather than inherited, hereditary titles are hereditary peers.
Many peers hold more than one hereditary title; for example, the same individual may be a duke, an earl, a viscount, and a baron by virtue of different peerages.
Since 1964, only five hereditary peerages have been granted—two (the Dukedom of York and the Earldom of Wessex) for members of the royal family, and three additional creations (the Viscountcy of Whitelaw, the Viscountcy of Tonypandy and the Earldom of Stockton) under Margaret Thatcher's government in the mid-1980s.

Hereditary factors clearly and strongly contribute to 5 percent to 10 percent of all breast cancer cases.
For example, hereditary breast cancer is also part of the rare hereditary cancer syndromes Li-Fraumeni syndrome and Cowden syndrome, which are associated with mutations in the p53 gene and the PTEN gene respectively.
Likewise, in some families, hereditary ovarian cancer may be associated with mutations that give rise to other syndromes that are distinguished by the patterns of cancer in the family.

 Hereditary Hemochromatosis Risk   (Site not responding. Last check: 2007-11-07)
Hereditary hemochromatosis is caused by inheriting an alteration, or mutation, in a gene that causes the body to store too much iron.
When one member of a family has been diagnosed with hereditary hemochromatosis other family members are also at increased risk for the disorder.
Thus, even though the fact that both your parents have been diagnosed with hereditary hemochromatosis guarantees that you have inherited two mutated genes, it doesn't mean that you will develop symptoms or get sick — especially if you and your doctor are aware of and take steps to regulate your own iron levels.

 Sloan-Kettering - Hereditary Cancer & Genetics: Overview
Hereditary cancer is the development of cancer due to an inherited gene mutation (changes in a specific gene) that has been passed from a parent to a child upon conception.
If a person has inherited such a gene mutation, he or she has inherited an increased risk to develop cancer in their lifetime, which is higher than the cancer risk of someone in the general population.
People who are interested in learning whether or not they have an increased likelihood of developing certain cancers or whether they inherited a gene, which contributed to their own or a family member's cancer, should consult with a specialist in the area of hereditary cancer, cancer risk assessment and genetic counseling and testing.
