In the modern science of todays world we choose what color world we want around us. We change our hair color, we change our eye color using contact lenses, and we manipulate and change whatever materials are around us and color them with a color that we favor at the moment. Today, in the world in fertility treatments and sperm donors there is discussion of choosing traits for your baby that will best fir the parents. It may actually be possible to choose the eye color of a baby before he or she is conceived. Theoretically, this could be done by choosing an egg and or sperm donor with the dominant eye color of your choice you can choose the eye color of your baby.
For example, a couple would like to have a baby with a similar appearance to them. They both have blond hair and blue eyes and the husband and wife have been unable to conceive with out medical intervention. They are concerned that if they have a dark haired baby with brown eyes that the baby will not bond with them as they would like. The wife is able to carry a child but they need both sperm and egg donors. They are planning on asking questions about the donor of the sperm and egg such as eye color. Eye color can be determined based on the eye color of the parents and also on the eye color of their parents. Any prediction will still be based on the principle of probability rather than on an actual choosing of eye color. Not all sperm and egg donor facility have such thorough records on donors. However, this is the next expectations of couples seeking in vitro fertilization. They desire to have a baby as close in appearance as possible including eye color.
Eye color is based on melanin, or brown coloring. This pigment in the iris gives the color to the eye. All new born babies eyes are blue at birth because the melanin is not yet produced in their eyes at birth. At least three genes are involved in the determination of eye color. Certain eye colors are dominant while others are recessive. No pigment at all is red. There are many eye colors shades and variants in color such as hazel, and grey, yet the main three eye colors are blue, green and brown. There is not yet a control over this area in science. There is merely educated predictions which in reality are still often educated guesses. Parents are closer to being able to choose eye color than ever before.
