Eye color is an inherited trait determined by multiple genes. [14] [15] These genes are sought by studying small changes in the genes themselves and in neighboring genes, called single-nucleotide polymorphisms or SNPs. The total number of genes that contribute to eye color is unknown, but there are a few likely candidates.
Exploration of the color space outside the range of "real colors" by this means is major corroborating evidence for the opponent-process theory of color vision. Chimerical colors can be seen while seeing with one eye or with both eyes, and are not observed to reproduce simultaneously qualities of opposing colors (e.g. "yellowish blue"). [7]
Color meaning is either based in learned meaning or biologically innate meaning. The perception of a color causes evaluation automatically by the person perceiving. The evaluation process forces color-motivated behavior. Color usually exerts its influence automatically. Color meaning and effect has to do with context as well. [12]
Your eye color could mean way more than a simple genetic pigmentation.
Green. Green hardly needs an introduction as a color—it's all around us! Just take a look outside, and you'll see it in the trees, the grass, and many other plants in the natural world.
A human chimera is a human with a subset of cells with a distinct genotype than other cells, that is, having genetic chimerism.In contrast, an individual where each cell contains genetic material from a human and an animal is called a human–animal hybrid, while an organism that contains a mixture of human and non-human cells would be a human-animal chimera.
According to Greek mythology, [1] the Chimera, Chimaera, Chimæra, or Khimaira (/ k aɪ ˈ m ɪər ə, k ɪ-/ ky-MEER-ə, kih-; Ancient Greek: Χίμαιρα, romanized: Chímaira, lit. 'she-goat') [ 2 ] was a monstrous fire-breathing hybrid creature from Lycia , Asia Minor , composed of different animal parts.
Trichromatic color vision is the ability of humans and some other animals to see different colors, mediated by interactions among three types of color-sensing cone cells. The trichromatic color theory began in the 18th century, when Thomas Young proposed that color vision was a result of three different photoreceptor cells .
