Which of the following is true concerning environment influence on gene activation?
A. A persons behavior influences the activation of some genes
B. The only time a gene can be influenced by environmental factors is during a person's growing years
C. All of a persons genes are activated at birth
D. Because DNA is embedded so deeply in a cell (in the nucleus) It is impossible to alter in any way the expression of a gene
Homework Answers
The behaviour of a person is heritable as well as affected by the environment. Expression or silencing of genes play a vital role in determining the behaviour of a person. The relationship between genes and behaviour is dynamic and keep changing as you gain new experiences.
So option A is correct

What is the main idea of gene-environment interaction? O genetics definitively determine all outcomes that occur in both appearance and behavior outcomes that are determined by genetics may or may not occur depending on the environment O environmental factors can only influence the expression of genes associated with negative behavior traits O the environment definitively determines all outcomes that occur in both appearance and behavior

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.
