No, brown eyes cannot turn blue in a baby.
Here's why:
-
Melanin's Role: Eye color is determined by the amount of melanin present in the iris. Melanin is a pigment that produces brown coloration. The more melanin, the darker the eyes.
-
Developmental Process: Babies are born with little melanin in their irises. As they age, their bodies produce more melanin. If a baby has genes for brown eyes, melanin production will increase, and their eyes will become brown.
-
Irreversible Change: The increase in melanin is a one-way process. Once the eyes become brown, the melanin level won't decrease enough for them to become blue. The color can only go from light to dark, not dark to light.
-
Blue Eyes: Babies with blue eyes have very little melanin in their irises. They have the genes for blue eyes, and melanin production never reaches a level where the eyes appear brown.
In short, if a newborn has dark eyes, they will not turn blue. This is because the presence of melanin indicates a genetic predisposition for darker eye color, and this process is not reversible.
