Your question: How do environmental factors affect the relationship between genotype and phenotype?

Environmental factors that play a role include how dry your mouth is or how recently you have eaten. The degree to which your phenotype is determined by your genotype is referred to as ‘phenotypic plasticity’. If environmental factors have a strong influence, the phenotypic plasticity is high.

How does the environment affect genotype and 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.

Can environmental factors affect the genotype?

Genotype generally remains constant from one environment to another, although occasional spontaneous mutations may occur which cause it to change. However, when the same genotype is subjected to different environments, it can produce a wide range of phenotypes.

How does the environment effect on the 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.

What is the cause and effect relationship between genotype and phenotype?

The sum of an organism’s observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism’s parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype.

How does the environment interact with genotypes?

In other words, each genotype responds similarly to the changing environment producing similar phenotypes. For all individual genotypes, average egg development time decreases with increasing temperature. The environment is influencing each of the genotypes in the same predictable manner.

What is the relationship between genotype and phenotype?

The genotype of an organism is defined as the sum of all its genes. The phenotype of an organism is the observable physical or biochemical characteristics of an organism, determined by both genetic make-up and environmental influences.

What factors affect phenotype?

An organism’s phenotype results from two basic factors: the expression of an organism’s genetic code, or its genotype, and the influence of environmental factors. Both factors may interact, further affecting phenotype.

What are two environmental factors that are likely to affect gene expression?

In addition to drugs and chemicals, temperature and light are external environmental factors that may influence gene expression in certain organisms.

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.

What are some environmental factors that can cause epigenetic changes?

Epigenetic marks can be affected by exposure to metals, air pollution, benzene, organic pollutants, and electromagnetic radiation [98]. Chemical and xenobiotic compounds in water or the atmosphere are other potential environmental stressors capable of changing epigenetic status.

What do you understand by phenotype and genotype give one example of each?

Physical characters of an individual that are observable, is the phenotype of that individual. A combination of alleles situated on corresponding chromosomes determines a person’s specific traits. The genes responsible for traits such color of the skin can be the example of a genotype.

How is transcription and translation related to genotype and phenotype?

Phenotype, such as the color of hair and eyes, is expressed in part through the processes of transcription and translation. Translation is the process by which the cell synthesizes proteins by reading mRNA strands and stringing together the appropriate amino acids. …
