Review/practice questions:
If brown eyes (B) are dominant over blue eyes (b) in humans, predict the outcome of the
following reproduction.
A true (homozygous) blue eyed father and a hybrid (heterozygous) brown eyed mother want to see
the probability for their children’s eye color.
1. What would be the genotype of the children?
2. What would be the phenotype of the children?

the passing of traits from parents to offspring.
It is in the molecule ________ that the information (the code) for traits is
contained. This molecule holds the “________________” code in the
sequence of ___________ that tell cells how to make its parts. There are
sections of the DNA code for specific traits, which are called
______________. The code in genes gives a cell the information to
make specific ___________________. The function (job) of these
specific proteins is what gives an organism its _______________.
