Polygenic inheritance and environmental effects. One of the animals is fed plentiful while the other is not sufficiently fed.
What is an example of a phenotype.
Discuss how environment can influence phenotype give one example. The environment can influence peoples behavior and motivation to act. The environment can influence mood. For example the results of several research studies reveal that rooms with bright light both natural and artificial can improve health outcomes such as depression agitation and sleep.
What is an example of a phenotype. Examples of phenotypes include height wing length and hair color. Just as the genotype influences the phenotype the environment will also influence the phenotype.
Several examples of the effect of the environment can be mentioned all of which contribute to variation of the phenotypic variation. Nutrition is an important element. Consider two animals containing the same genotype.
One of the animals is fed plentiful while the other is not sufficiently fed. This is the classic example of how an environmental factor can affect the expression of a gene. The rabbit has still got the same genesgenotype and the proteinenzyme is still made however the enviroment can determine if the enzyme does its job or not.
Thus the phenotype is affected by environment not genotype. Environmental effects on phenotype. SYI3 EU SYI3B LO SYI3B1 EK Google Classroom Facebook Twitter.
Environmental effects on phenotype. Polygenic inheritance and environmental effects. Environmental effects on phenotype.
Even when influenced by the environment phenotypes have a normal range of expression. For instance human height varies based on nutrition and genetics but not many people are shorter than 4½ feet or taller than 7 feet. The range of phenotypic possibilities is called the norm of reaction.
Hydrangeas for example may be blue pink or purple but they are never naturally orange. Hydrangeas are blue in acidic soil with available aluminum and they are. It means that many factors both genetic and environmental collectively influence phenotype truefalse Phenotype applies not only to specific physical characters but also to things like internal anatomy physiology and behavior.
Now the terms phenotype genotype and environmental influence will be considered. Generally it is a fact that the phenotype of an animal is determined by its genotype and its environment. 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.
The phenotype may change constantly throughout the life of an individual because of environmental changes and the physiological and morphological changes associated with aging. Different environments can influence the development of inherited traits as size for example is affected by available food supply and alter expression by similar genotypes for example twins maturing in dissimilar families. I can describe with examples how the environment can have an effect on the phenotype of an individual.
The enviroment can have an effect on the phenotype of an individual because environmental conditions can effect the expression of genes and influence traits that are geneticall determined. GENETICALLY identical individuals display a remarkable variation in phenotype. Differing histories of environmental exposure produce the phenotypic discordance.
Among examples are the different fingerprint patterns of identical twins and different coat patterns and personalities between cloned animals J ain et al. S hin et al. Give one example of how the environment can influence someones cultural identity What is your answer so far or What have you done so far as an attempt to solve this question.
If someone were to migrate from Afghanistan to a remote community in Australia they would probably find the change in their environment to have a negative influence on their cultural identity. Thus supporting the claim cause and effect that the environment has an influence on the phenotype of these plants. When plants grown in the dark were exposed to light they displayed the expected phenotype.
This supports the idea that environment does. Environment and Genetics Genes often interact with the environment creating different phenotypes depending on where the organism lives. The environment that influences a phenotype or trait can mean things like climate and location but it can also mean the food we eat the drugs we take or toxins that are around us.
