Цветы слабые. И простодушные. И они стараются придать себе храбрости. Они думают: если у них шипы, их все боятся...
She never looked nice. She looked like art, and art wasn't supposed to look nice; it was supposed to make you feel something.

The genetics of eye color are complicated, and blue color is determined by multiple genes. Some of the eye-color genes include EYCL1 (a green/blue eye-color gene located on chromosome 19), EYCL2 (a brown eye-color gene) and EYCL3 (a brown/blue eye-color gene located on chromosome 15). The once-held view that blue eye color is a simple recessive trait has been shown to be wrong. The genetics of eye color are so complex that almost any parent-child combination of eye colors can occur.[4][5]
In human eyes, these variations in color are attributed to varying ratios of eumelanin produced by melanocytes in the iris.[2] The brightly colored eyes of many bird species are largely determined by other pigments, such as pteridines, purines, and carotenoids.[6]
Three main elements within the iris contribute to its color: the melanin content of the iris pigment epithelium, the melanin content within the iris stroma, and the cellular density of the iris stroma.[7] In eyes of all colors, the iris pigment epithelium contains the black pigment, eumelanin.[2][7] Color variations among different irises are typically attributed to the melanin content within the iris stroma.[7] The density of cells within the stroma affects how much light is absorbed by the underlying pigment epithelium.[7] OCA2 gene polymorphism, close to proximal 5′ regulatory region, explains most human eye-color variation.[8]
