We dedicate this storybook to our wonderful biology teacher, Mrs. Mihatov.

A mother, who lived in a small suburban neighborhood with her husband and daughter, was pregnant with a baby girl. The two parents were very excited about expanding their family.



“Mommy, what is my little sister going to look like?” asked Emily.
Her mother didn’t know much about biology so she asked her husband to explain, “Robert, you're the biology teacher, why don’t you explain how genetics work to Emily.”



The father started by saying, “Your little sister is going to look like a mix of your mommy and daddy. I have brown hair and brown eyes, and your mother has blue eyes and blonde hair.”





Robert took out a piece of paper out and began to explain how to create a punnett square to Emily.
“This diagram is going to help us figure out what your sister will look like.”





“The figure shows us that your sister will have a 50% chance of having brown eyes and a 50% chance of having blue eyes.”
Emily secretly hoped that her sister would have brown eyes like hers.







“Well I want to find out what color hair she is going to have.”
Robert guided his daughter in putting down the right data into the punnett square by telling her that he was dominant for Brown hair, so he would get a big ‘B’. He also told her that Emily’s mother was recessive because she had blonde hair, so her trait would get a little ‘b’.
100% Brown Hair


“Emily, since I have two big ‘B’s, I am homozygous dominant, and since your mother has two little ‘b’s, she is homozygous recessive. By putting the letters together in the punnet square it will create a heterozygous dominant trait because there is a big ‘B’ and a little ‘b’. This means that the dominant trait will show because it hides the recessive trait.”
Emily told her father that her little sister was going to have the same brown hair that Emily had.


“Honey! It’s time for school!” Emily’s mother called out from outside. Emily was excited to show her teacher what her father taught her today.






At recess, Emily decided to show Ms. Smith what she learned at home. When the time came, Emily led her teacher over to a patch of flowers outside.








“See this white flower and this red flower? I’m going to show you what their baby flower will look like.”, Emily exclaimed, “Red is dominant so it will get a big ‘R’ and white is recessive so it will get a little ‘r’.”
“The baby flower will be red!”
