5. <strong>Sponge</strong> <strong>Bob</strong>’s aunt and uncle, <strong>Sponge</strong> Wilma and <strong>Sponge</strong> Wilbur, have the biggest roundeyes in the family. Wilma is believed to be heterozygous for her round eye shape, whileWilbur’s family brags that they are a pure line. Complete the Punnett square to show thepossibilities that would result if <strong>Sponge</strong> Wilma and <strong>Sponge</strong> Wilbur had children.(a) Give the genotype for each person.Wilma -_______ Wilbur -________(b) Complete the Punnett square to show the possibilitiesthat would result if they had children.(c) List the possible genotypes and phenotypes for thekids.5. <strong>Sponge</strong> <strong>Bob</strong>’s aunt and uncle, <strong>Sponge</strong> Wilma and <strong>Sponge</strong> Wilbur, have the biggest roundeyes in the family.

She knows that they have a 50% chance ofhaving a little roundpants, but is also hoping the new arrival will be blue (arecessive trait) like <strong>Sponge</strong>Susie and many members of her family.
