What are some environmental factors that can influence phenotype?

What factors influence phenotype?

Two factors that influence the phenotype are: (1) the specific genetic information of the individual (its genotype), and (2) environmental influences on the expression of the individual’s genetic potential.

How do environmental factors affect genes?

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 factors contribute to an individual’s phenotype give an example?

Phenotype is the observable physical or biochemical characteristics of an individual organism, determined by both genetic make-up and environmental influences, for example, height, weight and skin colour.

What are 3 examples of phenotypes?

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 gene expression in humans?

Generally, increasing temperature caused acceleration in development and the higher the temperature, the earlier the expression response of any specific targeted gene. In more detail, larval yolk utilization and growth rates increased, while yolk utilization efficiency decreased with increasing temperature.

Which of the following is an example of environmental impacts on the expression of traits?

Which of the following is an example of environmental impacts on the expression of traits? Animal coat color shifts in response to seasonal changes in day length and temperature.

Does the environment modify the phenotype give examples?

Environmental conditions, such as temperature and availability of nutrients can affect phenotypes. For example, temperature affects coat color in Siamese cats. … Height in humans is a complex phenotype influenced by many genes, but it is also influenced by nutrition.

What is the relationship between the environment and phenotype?

What is the relationship between the environment and phenotype? Environmental conditions can affect gene expression and influence genetically determined traits. Therefore the phenotype is affected by its genes as well as its environment.

Can phenotype change without a change in genotype?

Different phenotypes can be generated without changes to the genotype through a process called Epigenetics. Epigenetics, meaning “above genes”, is the study of changes to the phenotype caused by changes in gene expression and not the alteration of the genetic code.
