Dominant= large ears (HH)
Recessive= small ears (hh)

1) Create 2 tables that has 4
equal boxes inside of them.
2) Put Daisy’s genes (HH) on
the top of the Punnett Square
3) Put George’s genes (hh) on
the left side of the Punnett
Square

• Multiply the top letters by
the left side letters and then
write them down in each
box
• DO NOT forget the
dominant traits comes first

The Results!!!!!!!!
• Phenotype Results
The percentage that George and Daisy’s baby
will have big ears is 100%. There is a 0%
chance that the baby will have small ears.
• Genotype Results
The percentage that George and Daisy’s baby
will have Hh for a genetic code is 100%.
