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.

A. List the possible genotypes and phenotypes for their children.

B. Did the hospital make a mistake? Explain your answer.

ANSWERS

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.
