Essential Question
•
How does the environment
play a role in the expression
of our genes?
Think
1. Let’s say you have a gene that makes you
more likely to be overweight. If you eat
healthily and work out a lot, what will your
weight be like?
2. SO, do our genes determine EVERYTHING
about us?
3. What else influences what we look like?
Environment: your surroundings
Environment can influence gene expression =
you look one way in one environment, and
a different way in a different environment
Example:
in warm temps
red flowers
QuickTime™ and a
decompressor
are needed to see this picture.
in cool temps
purple flowers
Quick Time™ and a
decompressor
are needed to see this picture.
In a particular species of plants, when the soil pH is
greater than 7, blue flowers are produced.
However, when the soil pH is less than 7, pink
flowers are reproduced. Which statement best
explains the color change in the plant?
Environment 1: pH
__________
greater than 7 phenotype 1: __________
Blue flowers
Environment 2: __________
pH less than 7
phenotype 2: ___________
pink flowers
Environment influences gene expression
Examples of
phenotypes:
Blue eyes vs. brown eyes,
Red flowers vs. white flowers
Green pea vs. yellow pea
But do all traits just
come in 2 versions?
No!
What traits can you think
of that come in many
versions?
Height, skin
color, hair color
That’s because most
traits are controlled by
MANY genes
Polygenic trait:
Poly: many
Genic: genes
Polygenic trait: trait
controlled by MANY GENES
Polygenic traits usually
show a wide range of
phenotypes
Examples: height, skin color,
hair color

What is a polygenic trait?
EXIT TICKET
Provide 2 examples of polygenic traits.
In your own words, describe how the
environment can play a role in
determining the expression of certain
characteristics.
In a particular species of fish, when the
water is more salty, the fish has grey
scales, and white scales when in the
salinity (how salty the water is) is low. List
the two environments and the two
phenotypes.
For the question above, fill in the blanks:
Practice Problem
A man wants to investigate plant
height using pea plants: His pea
plants come in only 3 heights. He
has tall plants (TT), short plant (tt)
and medium plants (Tt). What are the
probable genotypes and
phenotypes?
