8. 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. Red = 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. • How many of the plants would have red flowers? • How many of the plants would have purple flowers? • How many of the plants would have blue flowers? % % %
