Bikini Bottom Genetics

Dive into Bikini Bottom Genetics! Practice Punnett squares and traits with this fun science worksheet.

Bikini Bottom Genetics Scientists at Bikini Bottoms have been investigating the genetic makeup of the organisms in this community. Use the information provided and your knowledge of genetics to answer each question. For each genotype below, indicate whether it is a heterozygous OR homozygous. Heterogeneous Bb He Ff Ss Ww Nn Homogeneous TT DD pp rr gg QQ Determine the phenotype for each genotype using the information provided about SpongeBob. Yellow body color is dominant to blue. YY yellow Yy yellow yy blue Determine the phenotype for each genotype using the information provided about SpongeBob. Square shape is dominant to round. SS square Ss square ss round For the phenotype below, give all of the possible genotypes for Patrick.A tall head (T) is dominant to short (t).Tall =Short = For the phenotype below, give all of the possible genotypes for Patrick.Pink body color (P) is dominant to yellow (p)Pink body =Yellow body = 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. Patrick met Patti at the dance. Both of them are heterozygous for their pink body color, which is dominant over a yellow body color. Create a Punnett square to show the possibilities that would result if Patrick and Patti had children. 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. Would Squidward’s children still be considered purebreds? Explain. 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. Mr. Krabbs and his wife recently had a Lil’ Krabby, but it has not been a happy occasion for them. Mrs. Krabbs has been upset since she first saw her new baby who had short eyeballs. She claims that the hospital goofed and mixed up her baby with someone else’s baby. Mr. Krabbs is homozygous for his tall eyeballs, while his wife is heterozygous for her tall eyeballs. Some members of her family have short eyes, which is the recessive trait. Create a Punnett square using T for the dominant gene and t for the recessive one. What are the possible genotypes and phenotypes for Mr. Krabs and his wife's children? Did the hospital make a mistake? Explain your answer.
