Red hair
Red hair (or ginger hair) occurs naturally in 1–2% of the human population. It occurs more frequently (2–6%) in people of northern or western European ancestry, and less frequently in other populations. Red hair appears most commonly in people with two copies of a recessive allele on chromosome 16 which produces an altered version of the MC1R protein. Red hair varies in hues from a deep burgundy or bright copper (reddish-brown or auburn) through to burnt orange or red-orange and strawberry blond. It is characterized by high levels of the reddish pigment pheomelanin and relatively low levels of the dark pigment eumelanin.
Human hair color
Hair color is the pigmentation of hair follicles due to two types of melanin: eumelanin and pheomelanin. Generally, if more eumelanin is present, the color of the hair is darker; if less eumelanin is present, the hair is lighter. The darker a person's natural hair color is, the more individual hair follicles they have on their scalp. Levels of melanin can vary over time causing a person's hair color to change, and it is possible to have hair follicles of more than one color on the same person. Particular hair colors are associated with ethnic groups. Gray or white hair is associated with age. The Fischer–Saller scale, named after Eugen Fischer and , is used in physical anthropology and medicine to determine the shades of hair color.
Melanocortin 1 receptor
The melanocortin 1 receptor (MC1R), also known as melanocyte-stimulating hormone receptor (MSHR), melanin-activating peptide receptor, or melanotropin receptor, is a G protein–coupled receptor that binds to a class of pituitary peptide hormones known as the melanocortins, which include adrenocorticotropic hormone (ACTH) and the different forms of melanocyte-stimulating hormone (MSH). MC1R is one of the key proteins involved in regulating mammalian skin and hair color. It is located on the plasma membrane of specialized cells known as melanocytes, which produce the pigment melanin through the process of melanogenesis.
Introduction to genetics
Genetics is the study of genes—what they are, what they do, and how they work. Genes inside the nucleus of a cell are strung together in such a way that the sequence carries information: that information determines how living organisms inherit various features (phenotypic traits). For example, offspring produced by sexual reproduction usually look similar to each of their parents because they have inherited some of each of their parents' genes. Genetics identifies which features are inherited, and explains how these features pass from generation to generation. In addition to inheritance, genetics studies how genes are turned on and off to control what substances are made in a cell—gene expression; and how a cell divides—mitosis or meiosis.
Ginger Kids
"Ginger Kids" is the eleventh episode in the ninth season of the American animated television series "South Park". The 136th episode of the series overall, it first aired on Comedy Central in the United States on November 9, 2005. The episode was written and directed by series co-creator Trey Parker. It caused controversy after its ironic premise was misunderstood by people who acted violently against redheads. In the episode, Cartman suffers from a mysterious and sudden onset of Gingervitus. Sick and tired of being ridiculed for his red hair, light skin and freckles, he rallies all the ginger kids everywhere to fight against discrimination and rise up and become the master race they are intended to be.

Red
Red is the colour at the end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. The red sky at sunset results from Rayleigh scattering, while the red color of the Grand Canyon and other geological features is caused by hematite or red ochre, both forms of iron oxide.

Argentines of European descent
European Argentines belong to several communities which trace their origins to various migrations from Europe, and which have contributed to the country's cultural and demographic variety. They are the descendants of colonists from Spain during the colonial period prior to 1810, or in the majority of cases, of Italians, Spanish and other Europeans who arrived in the great immigration wave from the mid 19th to the mid 20th centuries, and who largely intermarried among their many nationalities during and after this wave. No recent Argentine census has included comprehensive questions on ethnicity, although numerous studies have determined that European Argentinians have been a majority in the country since 1914.
White Africans of European ancestry
White Africans are people of European descent residing in, or hailing from, Africa who identify themselves as white. In 1989, there were an estimated 5.6 million Africans of European ancestry on the continent. Most are of Dutch, British, Portuguese, German, French, and to a lesser extent, Italian, Spanish, Greek or Irish descent. The majority once lived along the Mediterranean coast, in South Africa, or in Rhodesia. The earliest permanent European communities in Africa were formed at the Cape of Good Hope; Luanda, in Angola; São Tomé Island; and Santiago, Cape Verde through the introduction of Portuguese and Dutch traders or military personnel.
Mestizo
Mestizo (; Peninsular Spanish: , Latin American Spanish: ) is a term traditionally used in Spain and Latin America which originally meant a person of combined European and Amerindian descent, regardless of where the person was born. The term was used as an ethnic/racial category in the casta system that was in use during the Spanish Empire's control of their American colonies. Nowadays though, particularly in Latin America and the Philippines, Mestizo has become more of a cultural term, with culturally mainstream Latin Americans regarded or termed as Mestizos regardless of their actual ancestry, and with the term "Indian" being reserved exclusively for people who have maintained a separate indigenous ethnic identity, language, tribal affiliation, etc.
Short-term effects of alcohol consumption
The short-term effects of alcohol (also known formally as ethanol) consumption–due to drinking beer, wine, distilled spirits or other alcoholic beverages–range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), stupor, unconsciousness, anterograde amnesia (memory "blackouts"), and central nervous system depression at higher doses. Cell membranes are highly permeable to alcohol, so once alcohol is in the bloodstream it can diffuse into nearly every cell in the body. The concentration of alcohol in blood is measured via blood alcohol content (BAC).
Mexicans of European descent
European Mexicans are Mexican citizens of complete or predominant European descent. While the Mexican government periodically conducts racial censuses for "Indigenous Mexicans" and "Afro-Mexicans" it has not conducted a census for European Mexicans for nearly a century. Estimates of this ethnic group as a segment of the country's population range from 9% and 20% according to "The World Factbook" and Encyclopædia Britannica to as high as 47% according to the ENADIS 2010 (National Survey About Discrimination), conducted by the CONAPRED (National Council to Prevent Discrimination) as a mean to address the problems of racism that Mexicans of mainly Indigenous or African ancestry suffer at hands of a society that favors light skinned, European looking Mexicans.
New Zealanders
New Zealanders, colloquially known as Kiwis, are people associated with New Zealand, sharing a common history and culture. People of various ethnicities and national origins are citizens of New Zealand, governed by its nationality law. Originally composed solely of the indigenous Māori, the ethnic makeup of the population has been dominated since the 19th century by New Zealanders of European descent, mainly of Scottish, English, Welsh and Irish ancestry, with smaller percentages of other European ancestries such as German, Dutch, Scandinavian and South Slavic. Today, the ethnic makeup of the New Zealand population is undergoing a process of change, with new waves of immigration, higher birth rates and increasing interracial marriage resulting in the New Zealand population of Māori, Asian, Pacific Islander and multiracial descent growing at a higher rate than those of solely European descent, with such groups projected to make up a larger proportion of the population in the future.
Alcohol-induced respiratory reactions
Alcohol-induced respiratory reactions, also termed alcohol-induced asthma and alcohol-induced respiratory symptoms, are increasingly recognized as a pathological bronchoconstriction response to the consumption of alcohol that afflicts many people with a "classical" form of asthma, the airway constriction disease evoked by the inhalation of allergens. Alcohol-induced respiratory reactions reflect the operation of different and often racially related mechanisms that differ from those of classical, allergen-induced asthma. In 1973, Breslin et al. tested the effects of alcoholic beverage consumption on the respiratory symptoms of 11 asthmatic subjects who gave a history of asthma attacks following certain alcoholic beverages.
