How does the environment influence the appearance of an organism?

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.

How are genes affected by the environment?

Environmentally induced changes in gene expression occur when exposure to chemicals changes which genes are turned “on” or “off”—which can change how the cells function and thus a person's predisposition to disease. The effect of this chemical modification is called epigenetic regulation.

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 environmental influences mean?

1 external conditions or surroundings, esp. those in which people live or work. 2 (Ecology) the external surroundings in which a plant or animal lives, which tend to influence its development and behaviour. 3 the state of being environed; encirclement.

What are some environmental factors that can affect the growth of organisms?

So what environmental conditions can affect microbial growth? Temperature, oxygen, pH, water activity, pressure, radiation, lack of nutrients…these are the primary ones.

Which is an example of environmental influence on gene expression quizlet?

Environmental factors can affect gene expression such as: the production of skin pigmentation during exposure to sunlight in humans. In embryonic development, the embryo contains an uneven distribution of chemicals called morphogens.

How do environmental factors affect child development?

An enriching and stimulating home environment fosters healthy growth and brain development by providing a child with love, emotional support, and opportunities for learning and exploration. In families where only one parent is present, there are often fewer economic and emotional resources.

What are the five environmental factors?

Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.

Which of these 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. ... Height in humans is a complex phenotype influenced by many genes, but it is also influenced by nutrition.

How does genes and environment affect the development of a child?

Gene-Environment Interactions: The environment a child is exposed to both in utero and throughout the rest of his or her life can also impact how genes are expressed. For example, exposure to harmful drugs while in utero can have a dramatic impact on later child development.

How does biology and the environment affect human development?

Human development is a continuous, dynamic interplay between biology and environment. There are critical periods where the developing brain is especially responsive to early experiences. ... Environmental factors may affect child development differently depending on underlying individual genetic characteristics.

What are three factors that affect gene expression?

Various factors, including genetic makeup, exposure to harmful substances, other environmental influences, and age, can affect expressivity. Both penetrance and expressivity can vary: People with the gene may or may not have the trait and, in people with the trait, how the trait is expressed can vary.

How do environmental and genetic factors influence the growth of organisms?

How do environmental and genetic factors influence the growth of organisms? Genetic factors as well as local conditions affect the growth of organisms. − A variety of local environmental conditions affect the growth of organisms. Genetic factors affect the growth of organisms (plant and animal).

Which is an example of an environmental influence that would most likely result in natural selection?

Which is an example of an environmental influence that would most likely result in natural selection? - The soil in a field always has lots of nutrients, so corn plants in a population can grow quickly.
