Heredity Review-
Harry Munster
Through this review of heredity you will be drawing a picture of Harry Munster and his traits he
inherited from his parents. In your notebook draw a box for Harry about ½ a page big.
Note: Always underline a lower case letter in your punnett squares.
Harry’s Face Shape:
Harry’s dad has the dominant face shape of round (RR) and his mom has the recessive face shape of
oval (rr). Do a punnett square to find Harry’s face shape.
R

Draw Harry’s face shape.

Harry’s Eye Color:
Harry’s dad has the recessive eye color of blue (bb) and his mom has the dominant eye color of brown
(Bb). She is heterozygous for eye color. Create a punnett square.
How many squares came out heterozygous like mom?
What percent is that?
Harry is heterozygous like his mom. Draw his eye color.
Harry’s Eyebrows:
Harry’s dad has a dominant bushy uni-brow (UU) and his mom has the recessive thin uni-brow. Make a
punnett square.
Is Harry heterozygous for his eyebrow or is he homozygous?
What is his genotype for eyebrows?
Harry’s Nose:
Harry’s dad has a homozygous recessive pig shaped nose (pp) and his mom has a heterozygous pointy
witch nose (Pp). Create a punnett square.
Harry got the homozygous recessive phenotype. What does that phenotype look like?
What is his genotype?
What was the probability of him getting that shaped nose?
Harry’s Mouth:
Harry’s dad has the homozygous dominant genotype for fangs. His mom has the heterozygous genotype
for fangs. Create a punnett square. Use the letter (F or f) for fangs.
Now draw Harry’s phenotype for his mouth.
What was the probability of him getting fangs?
He could get two different genotypes. What were they?
Harry’s Hair:
Harry’s dad has blue curly hair which is recessive. His mom has blue straight spiky hair which is
dominant. Both have a homozygous genotype. Use the letter (S or s). Create a punnett square.
What is Harry’s genotype?
What is his phenotype?
What chance did he have to get that genotype and phenotype?
Draw Harry’s hair.
Harry’s Ears:
Harry’s dad has the heterozygous genotype for pointy elf ears. Harry’s mom has the same genotype.
Make a punnett square. Use the letter ( E or e).
Harry’s ears look just like his mom and dad’s.
What two genotypes could he have gotten?
Could have gotten something else?
Draw his phenotype.
What was that genotype?
