This fact proves the theory presented by some scientists that external objects and light conditions are also responsible to make the eye color. There are 7 million Cones present in the eyes to observe the colors. The white and black colors are identified with the help of 100 million rods. The eye color genetics is also connected with the number of cells and rods.


3. Genes are transferable:

It is a common fact about the genetics. The human genes are transmitted from parents to offspring. It is a common mode of genetic transformation. Parents with blue and brown eyes may have kids with black eyes. This example shows that there are high chances of variability. The eye color genes need to become dominant in order to show the full response. Without getting dominant situation, it is impossible for the color genes to give a new shape to your eyes. Blue eyed parents will produce kids with blue eyes. However, the level of color will be different in kids because of the genetic combinations.
