Inside pregnancy: Your baby's DNA

Inside pregnancy: Your baby's DNA

Let's take a minute to enter the mysterious world of genetics. The process starts at fertilization. The mother's and father's genetic codes bond, and the fertilized egg carries the baby's genetic code.

Genes are arranged in chains, like a string of pearls, called DNA. Every time a cell splits during the fetus's development, it creates an identical copy of itself in each cell. Each cell carries the genetic code that holds all of the fetus's traits.

DNA is a chain of codes about which more is unknown than known. DNA holds all of the genetic heredity that parents pass on to their children. Our eye color, our hair color, our blood type, and perhaps even some of our character traits are inscribed in our genes.

But not all is predestined. Genetic code combinations develop over time. They are influenced by the fetus's environment and will continue to be formed after birth.
