Genetics basics

Use your knowledge of genetics to answer these questions.

1. Indicate whether each genotype is a heterozygous (He) or homozygous (Ho).

TT _____ Pp _____ dd _____ Ff _____ Tt ____

Which ones would be considered purebred? ___________

2. In SpongeBob’s family, a yellow body color (Y) is dominant to blue (y) color. Determine the phenotype for each genotype below based on this information.

YY ______________ Yy ______________ yy ______________

3. If round eyeballs (R) are dominant to oval eyeballs (r), give the genotypes that are possible for members of SpongeBob’s family.

Round eyeballs = ______________ Oval eyeballs = _________________
