Science projectPeriod 11-15-14
Daisy, an African Elephant , and George, an Asian Elephant, cross-breed. Daisy (HH) has big ears, and George (hh) has small ears. What percentage of their babies will have small ears? What percentage of their babies will have big ears?
How to set up the Punnett Square
1) Create 2 tables that has 4 equal boxes inside of them.
H H
h
h
Genotype Box
Phenotype Box
George X Daisy hh HH Dominant= large ears
(HH)
Recessive= small ears (hh)
2) Put Daisy’s genes (HH) on the top of the Punnett Square3) Put George’s genes (hh) on the left side of the Punnett Square
How to solve your Punnett Square

Phenotype Genotype
Small ears hh
Big ears HH
• 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 then the recessive traits

The Results!!!!!!!!
• Phenotype ResultsThe 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 ResultsThe percentage that George and Daisy’s baby will have Hh for a genetic code is 100%.
