Editing Pedigree chart (section)

==In human use==
{{anchor|In human use}}In [[England]] and [[Wales]] pedigrees are officially recorded in the [[College of Arms]], which has records going back to the Middle Ages, including pedigrees collected during roving inquiries by its [[herald]]s during the sixteenth and seventeenth centuries. The purpose of these [[heraldic visitation]]s was to register and regulate the use of [[coats of arms]]. Those who claimed the right to bear arms had to provide proof either of a grant of arms to them by the College, or of descent from an ancestor entitled to arms. It was for this reason that pedigrees were recorded by the visitations. Pedigrees continue to be registered at the College of Arms and kept up to date on a voluntary basis but are not accessible to the general public without payment of a fee.

More visible, therefore, are the pedigrees recorded in published works, such as [[Burke's Peerage]] and Burke's [[Landed gentry|Landed Gentry]] in the United Kingdom and, in continental [[Europe]] by the [[Almanach de Gotha]].

A pedigree may be used to establish the probability of a child having a particular disorder or condition. It may be used to discover where the genes in question are located (x, y, or autosome chromosome), and to determine whether a trait is dominant or recessive. When a pedigree shows a condition appearing in a 50:50 ratio between men and women, it is considered [[Autosome|autosomal]]. When the condition predominantly affects males in the pedigree, it is considered [[X-linked recessive inheritance|x-linked]].<ref>[http://isite.lps.org/cbittle/web/documents/PedigreeCharts.pdf Pedigree Charts]isite.lps.org {{Webarchive|url=https://web.archive.org/web/20160306004043/http://isite.lps.org/cbittle/web/documents/PedigreeCharts.pdf |date=2016-03-06 }}</ref>

Some examples of dominant traits include [[male baldness]], [[astigmatism]], and [[dwarfism]]. Some examples of recessive traits include small eyes, little body hair, and tall stature.<ref>{{cite web |url=http://www.sciencebrainwaves.com/blogs/biology/genetics/dominant-and-recessive-genes-in-humans/ |url-status=dead |archive-url=https://web.archive.org/web/20120129210659/http://www.sciencebrainwaves.com/blogs/biology/genetics/dominant-and-recessive-genes-in-humans/ |archive-date=2012-01-29 |title=Dominant and Recessive Genes In Humans {{!}} Science Brainwaves}}</ref>
