Bikini Bottom Genetics Answer Key 1. Purebreds - TT, DD, BB, FF, ff, dd, bb, tt Hybrids - Dd, Bb, Ff, Tt 2. 3. Tall - TT or Tt Short - tt Pink - PP or Pp Yellow – pp 4. A. SS - square shape, Ss - square shape, and ss - round shape B. 2 out of 4 or 50% C. 2 out of 4 or 50% NOTE: Some of your students may feel that the roundpants gene should be the dominant trait as SpongeBob’s TV parents are both roundpants. However, these are only his parents on the TV show and his real parents are both heterozygous for squarepants. 5. 6. A. PP - pink body, Pp - pink body, and pp - yellow body B. 3 out of 4 or 75% C. 1 out of 4 or 25% b b B Bb Bb B Bb Bb 7. A. Bb - light blue skin B. 100% C. 0% D. Squidward’s children would not be considered purebred, since each would have a gene pair made up of a dominant gene and a recessive gene. A. TT - tall eyeballs or Tt - tall eyeballs B. The hospital must have made a mistake, since the genotype “tt” would not be possible based on the genotypes of Mr. and Mrs. Krabbs. NOTE: Students may come up with other possible scenarios, such as Mr. Krabbs not really a homozygous tall-eyed crab or a mutation. A few of my students suggested that Mr. Krabbs might not be the father! NOTE: Some of your students may comment that Mr. Krabbs was married to a whale. However, this was only for the TV show and he is happily married to a beautiful crab in real life. (Ok, so it’s not “real” life!)
