A characteristic showing quantitative inheritance such as SKIN PIGMENTATION in humans. (From A Dictionary of Genetics, 4th ed)
Function of the human eye that is used in bright illumination or in daylight (at photopic intensities). Photopic vision is performed by the three types of RETINAL CONE PHOTORECEPTORS with varied peak absorption wavelengths in the color spectrum (from violet to red, 400 - 700 nm).
Type of vision test used to determine COLOR VISION DEFECTS.
Coloration or discoloration of a part by a pigment.
A melanocortin receptor subtype found primarily in MELANOCYTES. It shows specificity for ALPHA-MSH and ADRENOCORTICOTROPIC HORMONE. Loss of function mutations of the type 1 melanocortin receptor account for the majority of red hair and fair skin recessive traits in human.
Ultrasonography applying the Doppler effect, with the superposition of flow information as colors on a gray scale in a real-time image. This type of ultrasonography is well-suited to identifying the location of high-velocity flow (such as in a stenosis) or of mapping the extent of flow in a certain region.
Disorders of increased melanin pigmentation that develop without preceding inflammatory disease.
Defects of color vision are mainly hereditary traits but can be secondary to acquired or developmental abnormalities in the CONES (RETINA). Severity of hereditary defects of color vision depends on the degree of mutation of the ROD OPSINS genes (on X CHROMOSOME and CHROMOSOME 3) that code the photopigments for red, green and blue.
Created 7 April 1992 as a result of the division of Yugoslavia.

Variant forms of the same gene, occupying the same locus on homologous CHROMOSOMES, and governing the variants in production of the same gene product.
Membrane transporters that co-transport two or more dissimilar molecules in the opposite direction across a membrane. Usually the transport of one ion or molecule is against its electrochemical gradient and is "powered" by the movement of another ion or molecule with its electrochemical gradient.
Tumors or cancer of the SKIN.
Corneal and conjunctival dryness due to deficient tear production, predominantly in menopausal and post-menopausal women. Filamentary keratitis or erosion of the conjunctival and corneal epithelium may be caused by these disorders. Sensation of the presence of a foreign body in the eye and burning of the eyes may occur.
Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.
Mutation process that restores the wild-type PHENOTYPE in an organism possessing a mutationally altered GENOTYPE. The second "suppressor" mutation may be on a different gene, on the same gene but located at a distance from the site of the primary mutation, or in extrachromosomal genes (EXTRACHROMOSOMAL INHERITANCE).

  • On the other hand, a recessive trait will be passed on only if both parents possess it. (encyclopedia.com)
  • The most obvious place to start is noting the color of the parents' eyes. (wikihow.com)
  • Subbotina/123RF When parents are expecting their first child, at some point during the nine-month waiting process, they naturally start to wonder what combination of traits the kid is likely to receive from each parent. (digitaltrends.com)
  • For some traits and users, the predictions can be very accurate, [when] both parents have very well known, high impact, dominant genetic markers. (digitaltrends.com)
  • Students are intrigued to learn exactly why they often exhibit traits similar to their parents. (flinnsci.com)
  • Students explore phenotypic differences in hair types found in the coats of different dog breeds, as they begin to learn about complex traits. (bioedonline.org)
  • Students test two alternative hypotheses to explain observable differences fruit fly eye color. (bioedonline.org)
  • In contrast, behavior is a hugely complex trait, and we don't even know what behavioral differences we're looking for in Neanderthals. (newyorker.com)
  • Survival upon infection and female fecundity exhibited differences in 50% and 40% of the tested isogenic vs. non-isogenic pairs, respectively, whereas all other traits were affected in only 10-25% of the cases. (g3journal.org)
  • Physiology, fitness and disease phenotypes are complex traits exhibiting continuous variation in natural populations. (g3journal.org)
  • Physiological, morphological, biochemical, behavioral, fitness and disease phenotypes exhibit continuous variation among natural populations and are therefore considered complex or quantitative traits. (g3journal.org)
  • The effects of these genes likely combine with those of OCA2 and HERC2 to produce a continuum of eye colors in different people. (medlineplus.gov)
  • Some of the eye-color genes include OCA2 and HERC2 . (wikipedia.org)
  • however, the main two genes associated with eye color variation are OCA2 and HERC2 , and both are localized in Chromosome 15 . (wikipedia.org)
  • PMID 19472299 ] Genotyping of five single nucleotide polymorphisms in the OCA2 and HERC2 genes associated with blue-brown eye color in the Japanese population. (snpedia.com)
  • Furthermore, it is clear how an individual with a lack of HERC2 function will have blue eyes (no pigment is made because OCA2 is not turned on). (kelseygroup.com)
  • This is also true the other way around-when OCA2 is not functioning, an individual will have blue eyes irrespective of the function of HERC2. (kelseygroup.com)
  • Some of these genes are also involved in skin and hair coloring. (medlineplus.gov)
  • Another condition called oculocutaneous albinism affects the pigmentation of the skin and hair in addition to the eyes. (medlineplus.gov)
  • Skin is without color. (slideserve.com)
  • Applying makeup, nail polish, dying one's hair, applying henna to the skin, and tooth whitening are not examples of acquired traits. (wikipedia.org)
  • Improved eye- and skin-color prediction based on 8 SNPs. (snpedia.com)
  • The most common nonscientific basis for racial classification is skin color. (religion-online.org)
  • Skin color is the favorite distinguishing feature because it is so easy to identify. (religion-online.org)
  • Whatever the primary index of race may be -- skin color, religion, or nationality -- this unscientific view of race presupposes certain inherited characteristics that all members of a given racial group have in common. (religion-online.org)
  • And different types of humans have always been involved, not just fair eyed, humanity is seeded from the cosmos and is closer to the sun than outer planets, and skin/eyes/hair has alot to do with a planet's proximity to the sun, and also cloud cover. (abovetopsecret.com)
  • A 2012 study from the journal Nature , found that the pigment pheomelanin, which gives hair the red color, makes redheads more susceptible to the melanoma than fair-skinned blonds, even when they cover up their skin. (go.com)
  • This pigment is responsible for giving eyes, hair, and skin its color. (kelseygroup.com)
  • In Uncle Tom's Cabin, Harriet Stowe clearly describes a community where the individual's social status is created more by the color of the skin than by his own personal values. (bartleby.com)
  • Systems based on single nucleotide polymorphisms for accurate prediction of iris, hair and skin color in global population, independent of bio-geographical ancestry, have recently been introduced. (springer.com)
  • Here, we analyzed 14 SNPs for distinct skin pigmentation traits in a homogeneous cohort of 222 Polish subjects. (springer.com)
  • We demonstrate Random Forest to be the most accurate algorithm for 3- and 4-category estimations (total of 58.3% correct calls for skin color prediction, 47.2% for tanning prediction, 50% for freckling prediction). (springer.com)
