What factors affect 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.
What are 3 environmental factors that can affect traits?
Explanation: Organisms are born with specific traits inherited from their parents, but the environment can influence them.
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 are some examples of environmental factors?
Environmental factors include temperature, food, pollutants, population density, sound, light, and parasites.
What is the relationship between environment and phenotype?
Often it is assumed that the phenotype is the sum of the genotype and the environment . The phenotype can also be seen as the interaction between genetics and environmental factors, some genotypes are better in one environment and others are better in another environment .
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 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.
When environmental factors influence gene expression this is referred to as?
When environmental factors influence gene expression, this is referred to as: multifactorial inheritance. If two alleles code for the same trait (such as blond hair), they are said to be: homozygous.
How does the environment affect phenotypic expression?
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 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.
