Can Asians Have Blue Eyes? Dominant and Recessive genes - Nonsense Collection

As geneticists have made interesting discoveries over the past few years, I always wanted to know if anyone has been able to trace the origination of Asian eyes. It is quite easy to identify whether a person is from Asia; they have small, almond-shaped, and slanty eyes. Although this is a common characteristic, they also have big, round eyes. Most people assume that the epicanthal fold is the main feature for identifying Asians. Also, when you look at the brow ridge, you can see it continuing with their eyes. Due to this reason, their eyelids are flat, instead of sloping inwards. To trace the origins of Asian eyes, you have to go through large volumes of genetic analyses, artifacts, and fossil records.

Genotype vs Phenotype

Everyone with blue eyes alive today — from Angelina Jolie to Wayne Rooney — can trace their ancestry back to one person who probably lived about 10, years ago in the Black Sea region, a study has found. Scientists studying the genetics of eye colour have discovered that more than This indicates that the mutation originated in just one person who became the ancestor of all subsequent people in the world with blue eyes, according to a study by Professor Hans Eiberg and colleagues at the University of Copenhagen. The scientists are not sure when the mutation occurred but other evidence suggested it probably arose about 10, years ago when there was a rapid expansion of the human population in Europe as a result of the spread of agriculture from the Middle East.

Gaining a deep insight into human evolution, researchers have identified a mutation in a critical human gene as the source of several distinctive traits that make East Asians different from other races. The traits — thicker hair shafts, more sweat glands, characteristically identified teeth and smaller breasts — are the result of a gene mutation that occurred about 35, years ago, the researchers have concluded. The discovery explains a crucial juncture in the evolution of East Asians.
