1. Fill out the chart.
Inherited Traits
Acquired Traits
Where do we get
them from?
4+ Examples of
Physical Traits
3+ Examples of
Behavioral
Traits
2+ Examples of
Medical traits
2. Do acquired traits affect your genotype, your phenotype, both, or neither? Explain your answer.
3. Draw and label the GENOTYPES and PHENOTYPES of a person who is:
a. Homozygous recessive for eye
d. Homozygous recessive for hairline
color
e. Heterozygous for hair texture
b. Heterozygous for hair color
f. Homozygous dominant for lip
c. Homozygous dominant for chin
shape
shape
g. Heterozygous for eye shape
4. Bayron says it’s possible for a parent with a dominant phenotype to have children with a recessive
phenotype, yet Aliyah impossible for a parent with recessive phenotypes to have a child with
dominant phenotypes. How could they both be right? Provide a SPECIFIC example for EACH CASE
and use a PUNNET SQUARE to explain.
5. A man and a woman decide to have a child.
a. The man is homozygous dominant for hair color, while the woman is heterozygous.
b. Both have blue eyes
c. Both have straight hairlines.
d. Both are heterozygous for lip shape.
e. Mom is homozygous recessive for face shape, while the dad is homozygous dominant.
If they only have ONE CHILD, write a 5 sentence paragraph explaining what the child will MOST
LIKELY look like OR draw a picture and label genotypes/phenotypes. Make sure to use PUNNET
SQUARES to help your evidence.
Punnet Squares, Genotypes &
Phenotypes of Parents and
possible Child
Ideas of what the child will most
likely look like (labeled picture or
5 sentence paragraph)
Support your answer—here,
explain the REASON how you
know.
6. Imagine you are on the committee for deciding who will, for the first time, gain the prestigious
Nobel Prize after death. If you had to choose between giving it to Gregor Mendel, or Rosalind
Franklin, who would you give it to and why? Make sure you include a reason why you would NOT
give it to the other person. MAKE SURE YOUR ANSWER IS NOT EMOTIONAL but DESCRIBES the
DISCOVERIES EACH SCIENTIST MADE!
7. EXTRA CREDIT: What are two ways I can illustrate or show the location of a gene?
8. EXTRA CREDIT: Draw and explain the processes of transcription and translation.
