Directions:
To determine which traits your baby will have, you will flip a coin to decide whether each
allele is dominant or recessive.
You will flip a coin twice for each trait. The first flip will determine the allele from the
mother and the second flip will determine the allele from the father. A heads on the coin
will be dominant (capital letter) and a tails will be recessive (lower case letter).
Repeat the coin flip for each allele.
First, flip for the gender; heads will give you an X (girl), tails gives you a Y (boy)
