2.Use the information for SpongeBob’s traits to write the genotype (s) for each item.

a. Yellow body - e. Stubby nose –

b. Round pants - f. Round eyes –

c. Oval eyes - g. Square pants -

d. Long nose - h. Blue body -

3. Determine the phenotype for each genotype using the information provided about SpongeBob.

Yellow body color is dominant to blue.YY _________ Yy ________ yy ________Square shape is dominant to round.SS _________ Ss ________ ss _________

4. For each phenotype, give the genotype that are possible for Patrick.

A tall head (T) is dominant to short (t)Tall = _______________________Short = ______________________

Pink body color (P) is dominant to yellow (p)Pink body = ________________________Yellow body = ______________________
