Bikini Bottom Genetics Scientists at Bikini Bottom 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. 1. Fill out the chart below with the requested information. Genotype TT Bb DD Ff tt dd Dd ff Tt bb Heterozygous (He) or Homozygous (Ho) Ho Dominant (Dom) or Recessive (Rec)? Dom Purebred (Pure) or Hybrid (Hyb) Pure 2. Use the information provided below, and fill out the chart below with the requested information. Trait Dominant Gene Recessive Gene Body Shape Squarepants (S) Roundpants (s) Body Color Yellow (Y) Blue (y) Eye Shape Round (R) Oval (r) Nose Style Long (L) Stubby (l) Description heterozygous for body shape purebred (dominant) for nose style homozygous recessive body color homozygous dominant for body color hybrid for nose style homozygous dominant for body shape homozygous recessive for nose style heterozygous for eye shape purebred (recessive) for body shape heterozygous for body color homozygous dominant for eye shape Genotype Ss Phenotype squarepants 3. 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 shape (S) is dominant over round (s). A. List the possible genotypes and phenotypes for their children. Genotype Phenotype B. What are the chances of a child with a square shape? ____% C. What are the chances of a child with a round shape? ____% 4. Patrick met Patti at the dance. Both of them are heterozygous for their pink body color (P), which is dominant over yellow body color (p). Create a Punnett square to show the possibilities that would result if Patrick and Patti had children. A. List the possible genotypes and phenotypes for their children. Genotype Phenotype B. What are the chances of a child with a pink body? ____% C. What are the chances of a child with yellow body? ____% 5. Everyone in Squidward’s family has light blue skin (B), which is the dominant over green skin (b) in his town. His family brags that they are all “purebreds.” He recently married a nice girl who has light green skin. Create a Punnett square to show the possibilities that would result if Squidward and his new bride had children. A. List the possible genotypes and phenotypes for their children. Genotype Phenotype B. What are the chances of a child with light blue skin? ____% C. What are the chances of a child with light green skin? ____% D. Would all of Squidward’s children still be considered purebreds? Explain! _________________________________ ________________________________________________
