The llama and alpaca are only known in the domestic state, and are variable in size and color, being often white, black, or piebald. The wild guanaco and vicuña are of a nearly uniform light-brown color, passing into white below. The vicuña and guanaco share an obvious family resemblance and may be difficult to tell apart at a distance.
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.
The guanaco (/ ɡ w ɑː ˈ n ɑː k oʊ / ghwuah-NAH-koh; [3] Lama guanicoe) is a camelid native to South America, closely related to the llama. Guanacos are one of two wild South American camelids; the other species is the vicuña, which lives at higher elevations.
The diameter of llama wool's fiber varies between 20 and 80 micrometers, depending on whether the llamas were raised for its wool or as a pack animal. The guanaco ( Lama guanicoe ) is a wild camelid, standing at 100–120 cm (39–47 in) at the shoulder [ 6 ] and 150–160 cm (59–63 in) at the head.
The red-eye effect in photography is the common appearance of red pupils in color photographs of human eyes. It occurs when using a photographic flash at low lighting or at night. When a flash passes through the eyes and rebounds at the back of the eye, it causes a red reflex in an image, turning the subject's eyes red.
The four pigments in a bird's cone cells (in this example, estrildid finches) extend the range of color vision into the ultraviolet. [1]Tetrachromacy (from Greek tetra, meaning "four" and chroma, meaning "color") is the condition of possessing four independent channels for conveying color information, or possessing four types of cone cell in the eye.
