Gene Expression
Interaction of Environment and Genetic Expression
• Phenotype is affected by genotype and by the
environment.
• Temperature
• Light
• Nutrition
• Chemicals
• Infectious Agents
• Himalayan rabbits and Arctic foxes
o Cold temperatures induce different coat colors.
Spring

Winter

• Chlorophyll production in
plants
o Plants, such as grass,
that lack exposure to
the sun cease to
produce chlorophyll.
• Identical twins
o Identical twins are not
phenotypically identical
due to environmental
differences inside the
womb and outside the
womb.
o Different
fingerprints
