There are several examples where environment influences gene expression.. For example, the freguency of an albino being born is 1 in 20,000, but in Hopi village for example, the frequency is 1 in 200. This is because they favour the trait by having consanguinous marriages often and hence the frequency increases. In another example, two flowers may have the same genetic make-up, but one may be blue and one maybe pink due to the difference in pH they can tolerate. The blue flower maybe blue due to low pH and the pink flower maybe pink due to high pH. The most common example however is when two monozygous twins (twins having the same genetic make up and also the same features) live in different environments, there will be remarkable difference in the two and you can tell just by looking at them. Thus, it is now only genes that decide how we look and act but also the environment that plays an equally important role in determining gene expression. Hope ur clear about it now.. cheers!
Characteristics are determined by the interaction between genes and the environment. Genes provide the blueprint for traits, but how they are expressed can be influenced by external factors such as diet, lifestyle, and experiences. This interaction between genes and the environment is known as gene-environment interaction.
The genotype and the environment both affect a phenotype.
Genes produce proteins that cause traits.
Interactions between genes and the environment can influence phenotype by modifying gene expression levels. Environmental factors like diet, stress, and exposure to pollutants can impact gene regulation, leading to different phenotypic outcomes. For example, identical twins with the same genetic makeup can exhibit differences in traits like height or disease susceptibility due to environmental influences.

Genes and the Environment. -Novanet :)
Genes and environment are the two main factors that work together to affect an organism's phenotype.
Natural selection acts on the way organisms interact with one another and with their environment. The genes of organisms are not usually themselves involved in this interaction: they direct it through intermediaries such as proteins. So natural selection must work through these intermediaries to affect genes.
yes it can affect the coding of genes.
The best way to test the effect of genetic versus environment is to conduct studies in identical twins because one can never hold environment perfectly constant, but identical twins are perfect genetic matches. Studies show that behavioral traits like sexual preference, depression, schizophrenia and other cognitive and behavioral disorders and even preferences are mostly shaped by environment, and have a very minor genetic component.
There are many genes that could affect a person's weight. This is accomplished by suppressing certain fat burning genes in the body.
The dominant genes take over, and then the recessive genes hide away
