Scientists at Bikini Bottoms have been investigating the
genetic makeup of the organisms in this community.
Complete each section.
For each genotype below, indicate whether it is a
heterozygous (He) OR homozygous (Ho).
SpongeBob loves growing flowers for his pal Sandy!
Her favorite flowers, Poofkins, are found
in red, blue, and purple. Use the
information provided and your
knowledge of incomplete dominance to
complete each section.
Identify the correct genotype for each flower color below if R
represents a red gene and B represents a blue gene.

Blue =
Purple =
What would happen if SpongeBob crossed a Poofkin with red flowers with a Poofkin with
blue flowers? Complete the Punnett Square to determine the chances of each flower
color.
