Phenotype and GenotypeTrait Dominant gene Recessive gene
Body shape Squarepants (S) Roundpants (s)
Body color Yellow (Y) Blue (y)
Eye shape Round (R) Oval (r)
Nose style Long (L) Stubby (l)
1.Use the information for SpongeBob’s traits to write the phenotype for each item.
a. LL – b. yy - c. Ss -
d. RR – e. Rr - f. ll -
g. ss – h. Yy -

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 = ______________________
