15 Weeks Pregnant: Your Pregnancy Week by Week - Page 2

What will your baby look like?

There is no way to know for sure what your baby will look like but you can take some guesses based on which genetic features are dominant and which are recessive. What your baby will look like is determined by the genes that she gets from her mom and dad. Each person gets two copies of each gene, one from mom and one from dad. If a genetic trait is dominant, your baby only needs to receive one copy of this gene for the trait to be expressed. If it is recessive, he will need to have to copies of this recessive gene in order for the trait to be expressed.

Here are a few examples of dominant and recessive traits that your baby could have.

Hair - Dark hair is the dominant trait. Blonde and red hair are recessive. Curly hair is dominant and straight hair is recessive.

Eye color - Brown eyes are dominant and blue, green or hazel eyes are recessive.

Dimples and freckles - Dimples and freckles are dominant traits.
