Hello, I'm a genetic counselor with a background in biology and genetics. When it comes to predicting a baby's eye color, it's important to understand that this trait is determined by multiple genes, with the most significant being the OCA2 and HERC2 genes located on chromosome 15.
Eye color is a polygenic trait, which means it's influenced by more than one gene. The inheritance pattern isn't as straightforward as some other traits, and it's also affected by the interactions between different versions of these genes, a phenomenon known as epistasis.
In general, brown is the most common eye color and is considered dominant to blue and green. This means that if a child inherits a gene for brown eyes from one parent and a gene for blue or green eyes from the other, the child will most likely have brown eyes. However, there are many variations and combinations of genes that can result in different eye colors.
To give a more precise prediction, we would need to know the specific genetic makeup of both parents. But even with that information, predicting eye color with absolute certainty is not possible due to the complex genetic interactions involved.
Here's a simplified way to look at it: If both parents have brown eyes, the chances are high that their children will also have brown eyes. If one parent has blue eyes and the other has brown, the child could have either color, but statistically, brown is more likely due to its dominance. If both parents have blue eyes, the child is very likely to have blue eyes.
Please remember that this is a general guideline and individual genetic variations can lead to different outcomes.

Most of the new born babies have blue eyes, which may change color over time. The eyes remain blue if both the parents pass their recessive blue genes to the child. ... However, the original color, be it brown, green, blue or hazel, will be determined over time.
