The total number of genes that contribute to eye color is unknown, but there are a few likely candidates. A study in Rotterdam (2009) found that it was possible to predict eye color with more than 90% accuracy for brown and blue using just six SNPs. [16] [17] In humans, eye color is a highly sexually dimorphic trait. [18]
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [ 1 ] it is characterized by the bilateral degeneration of the retina , causing progressive vision loss culminating in blindness.
Domestic cat with complete heterochromia, also referred to as an odd-eyed cat. Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. Although the processes determining eye color are not fully understood, it is known that inherited eye color is determined by multiple genes ...
Lentigo in cats is a common dermatological condition characterized by the presence of small, flat, brownish spots on the skin — particularly around the lips, nose, and eyelid margins. Unlike in ...
One of the cat diseases caused by malnutrition is central retinal deficiency, a dysfunction in cats that can be hereditary as well. [14] The retina, a thin layer of tissue in the back of the eye, is the structure affected by this disorder.
White cats having one blue and one other-colored eye are called "odd-eyed" and may be deaf on the same side as the blue eye. [16] This is the result of the yellow iris pigmentation rising to the surface of only one eye, as blue eyes are normal at birth before the adult pigmentation has had a chance to express itself in the eye(s).
Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3 ...
A Las Vegas family is stressing the importance of parental instincts after their 11-year-old Elijah Portillo collapsed in school. While his mom and dad knew something was wrong, doctors said ...
