It is possible for two parents each with brown eyes to produce a blue-eyed child.
a. true
b. false

True

Explanation:

The color of the baby's eyes is influenced by the genetic inheritance (of the genes transmitted by the mother and father) and the amount of melanin (brown or black pigment whose type and amount is encoded in the genes) found in the iris.

Eye color is controlled by at least three genes, although researchers still only understand the role of two of them. Determining eye color is an extremely complex process and there are several conditioning factors and genetic combinations that can influence the final color.

The more melanin, the darker the color of eyes, skin and hair. If parents have both brown eyes, it is natural for their children to have the same color. However, there may be a genetic influence from an ancestor and the child expressing a different color.

If the presence of melanin in the iris is reduced, the baby will have blue eyes, even if father and mother have brown eyes. If the presence of melanin is higher, the eye color will be green or hazel. When there is a large production of melanin, the eyes are brown, predominant color over green or blue and therefore more common. The least common color is green.

imagine a line passing through the center of earth that goes through both the north pole and the south pole. this imaginary line is called an axis. earth spins around its axis, just as a top spins around its spindle. this spinning movement is called earth's rotation. at the same time that the earth spins on its axis, it also orbits, or revolves around the sun. this movement is called revolution.

ok yes, but what is the question? as soon as you ask the actual question i will answer it. : )
