Abstract

The article focuses on the biological basis of eye colour and colour vision in humans. Eye colour is determined by the amount and type of melanin stored in melanosomes within the iris, influenced by over 150 genes inherited from parents. Colour vision occurs through photoreceptor cells in the retina—rods for low light and cones for colour detection—allowing humans to distinguish up to 10 million colours. The article also explains that males are more prone to red-green colour blindness due to genetic differences on the X chromosome. Additionally, it notes that dogs perceive colour differently, having only two types of cones compared to humans’ three. [Extracted from the article]
