6. Everyone in Squidward's family has light blue skin, which is the dominant trait for body color in his hometown of Squid Valley. His family brags that they are a "purebred" line. He recently married a nice girl
who has light green skin, which is a recessive trait. Create a Punnett square to show the possibilities that would
result if Squidward and his new bride had children. Use B to represent the dominant gene and b to represent
the recessive gene.
A. List the possible genotypes and phenotypes for their children.

D. Would Squidward's children still be considered purebreds? Explain!
They wouldn't be considerd pure bred. Each has a gene
made of a dominant and ressive gene.
7. Assume that one of Squidward's sons, who is heterozygous for the light blue body color, married a girl that
was also heterozygous. Create a Punnett square to show the possibilities that would result if they had children.
