Mendelian inheritance is a type of biological inheritance following the principles originally proposed by Gregor Mendel in 1865 and 1866, re-discovered in 1900 by Hugo de Vries and Carl Correns, and later popularized by William Bateson. These principles were initially controversial. When Mendel's theories were integrated with the Boveri–Sutton chromosome theory of inheritance by Thomas Hunt Morgan in 1915, they became the core of classical genetics. Ronald Fisher combined these ideas with the theory of natural selection in his 1930 book The Genetical Theory of Natural Selection, putting evolution onto a mathematical footing and forming the basis for population genetics within the modern evolutionary synthesis.
The Purple Heart (PH) is a United States military decoration awarded in the name of the president to those wounded or killed while serving, on or after 5 April 1917, with the U.S. military. With its forerunner, the Badge of Military Merit, which took the form of a heart made of purple cloth, the Purple Heart is the oldest military award still given to U.S. military members. The National Purple Heart Hall of Honor is located in New Windsor, New York.
Purple is a color similar in appearance to violet light. In the RYB color model historically used in the arts, purple is a secondary color created by combining red and blue pigments. In the CMYK color model used in modern printing, purple is made by combining magenta pigment with either cyan pigment, black pigment, or both. In the RGB color model used in computer and television screens, purple is created by mixing red and blue light in order to create colors that appear similar to violet light.
The Color Purple is a 1982 epistolary novel by American author Alice Walker that won the 1983 Pulitzer Prize for Fiction and the National Book Award for Fiction.
Deep Purple are an English rock band formed in London in 1967. They are considered to be among the pioneers of heavy metal and modern hard rock, but their musical approach has changed over the years. Originally formed as a psychedelic rock and progressive rock band, they shifted to a heavier sound with their 1970 album Deep Purple in Rock. Deep Purple, together with Led Zeppelin and Black Sabbath, have been referred to as the "unholy trinity of British hard rock and heavy metal in the early to mid-seventies". They were listed in the 1975 Guinness Book of World Records as "the globe's loudest band" for a 1972 concert at London's Rainbow Theatre and have sold over 100 million albums worldwide.
In Greek mythology, the Golden Fleece is the fleece of the golden-woolled, winged ram, Chrysomallos, that rescued Phrixus and brought him to Colchis, where Phrixus then sacrificed it to Zeus. Phrixus gave the fleece to King Aeëtes who kept it in a sacred grove, from whence Jason and the Argonauts stole it with the help of Medea, Aeëtes' daughter. The fleece is a symbol of authority and kingship.
Tyrian purple, also known as royal purple, imperial purple, or imperial dye, is a reddish-purple natural dye. The name Tyrian refers to Tyre, Lebanon, once Phoenicia. It is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex. In ancient times, extracting this dye involved tens of thousands of snails and substantial labour, and as a result, the dye was highly valued. The colored compound is 6,6'-dibromoindigo.
Purpura is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes. They measure 3–10 mm, whereas petechiae measure less than 3 mm, and ecchymoses greater than 1 cm.
Rhodobacterales are an order of the Alphaproteobacteria.
The Ectothiorhodospiraceae are a family of purple sulfur bacteria, distinguished by producing sulfur globules outside of their cells. The cells are rod-shaped, vibrioid, or spirilla, and they are able to move using flagella. In general, they are marine and prefer anaerobic conditions. Ectothiorhodospiraceae are a vibrio bacteria that require salty living conditions to survive and grow: classifying them as slightly halophilic. Like all purple sulfur bacteria, they are capable of photosynthesis. To complete this energy process, Sulfur compounds are used as electron donors for carbon fixation in the pentose phosphate pathway. This elemental sulfur accumulates outside of the cells.
Palatinate or palatinate purple is a purple colour associated with Durham University and the County and City of Durham. The term has been used to refer to a number of different shades of purple.

Purple acid phosphatases (PAPs) (EC 3.1.3.2) are metalloenzymes that hydrolyse phosphate esters and anhydrides under acidic condition. In their oxidised form, PAPs in solution are purple in colour. This is due to the presence of a dinuclear iron centre, to which a tyrosine residue is connected via a charge transfer. This metallic centre is composed of Fe3+ and M, where M is Fe3+, Zn2+, Mg2+ or Mn2+. The conserved Fe3+ is stabilised in the ferric form, whereas M may undergo reduction. Upon treatment with mild reductants, PAPs are converted to their enzymatically active, pink form. Treatment with strong reducing agents dissociates the metallic ions, and renders the enzyme colourless and inactive.
Colyer is a small unincorporated community south of the borough of Centre Hall in central Potter Township, Centre County, Pennsylvania, United States.
The purple-crowned fairywren is a species of bird in the Australasian wren family, Maluridae. It is the largest of the eleven species in the genus Malurus and is endemic to northern Australia. The species name is derived from the Latin word cǒrōna meaning "crown", owing to the distinctive purple circle of crown feathers sported by breeding males. Genetic evidence shows that the purple-crowned fairywren is most closely related to the superb fairywren and splendid fairywren. Purple-crowned fairywrens can be distinguished from other fairywrens in northern Australia by the presence of cheek patches and the deep blue colour of their perky tails.
GPR113 is a gene that encodes the Probable G-protein coupled receptor 113 protein.
Color symbolism in art, literature, and anthropology refers to the use of color as a symbol in various cultures and in storytelling. There is great diversity in the use of colors and their associations between cultures and even within the same culture in different time periods. The same color may have very different associations within the same culture at any time. Diversity in color symbolism occurs because color meanings and symbolism occur on an individual, cultural and universal basis. Color symbolism is also context-dependent and influenced by changes over time. Symbolic representations of religious concepts or articles may include a specific color with which the concept or object is associated.
