Draw

SpongeBob SquarePants recently met SpongeSusie Roundpants at a dance. SpongeBob is heterozygous for

his square shape, but SpongeSusie is round.

Create a Punnett square to show the possibilities that would

result if SpongeBob and SpongeSusie had children. Square = R, round = r.

Draw

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.

Draw

SpongeBob’s aunt is famous around town for her itty, bitty stubby nose! She recently met a cute

squarepants fellow who also has a stubby nose, which is a recessive trait. Would it be possible for them to

have a child with a regular long nose? Why or why not?

Create a Punnett square to help you answer this

question.
