What is an example of an environmental effect on phenotype?

Environmental conditions, such as temperature and availability of nutrients can affect phenotypes. For example, temperature affects coat color in Siamese cats.

How does the environment affect phenotype?

Environment Can Impact Phenotype



Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal’s genes are expressed, which ultimately affects the animal’s phenotype.

Which is an example of environmental influence on gene expression?

Drugs and Chemicals. The presence of drugs or chemicals in an organism’s environment can also influence gene expression in the organism. Cyclops fish are a dramatic example of the way in which an environmental chemical can affect development.

What are 3 examples of phenotype?

Phenotype Examples

  • Eye color.
  • Hair color.
  • Height.
  • Sound of your voice.
  • Certain types of disease.
  • Size of a bird’s beak.
  • Length of a fox’s tail.
  • Color of the stripes on a cat.

How does temperature affect phenotype?

Increases in temperature (warm environments) showed a non-significant increase in phenotypic means and a marginally significant increase in phenotypic variability. Larger increases in temperature saw greater increases in phenotypic variability, but no increase in the mean phenotypic response.

What traits are influenced by the environment?

Explanation: Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.

What are the five environmental factors?

What are some examples of environmental traits?

Examples of environmental traits are your favorite music, being a good basketball player, and the language you speak. These traits are environmental traits because they are traits that you choose or learn, or that are influenced by the place you live.

How does the environment affect gene expression in humans?

Environmental factors such as food, drugs, or exposure to toxins can cause epigenetic changes by altering the way molecules bind to DNA or changing the structure of proteins that DNA wraps around.

What are the examples of phenotype?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
