For the experssion of traits genes provide only the potentiality and the enivornment provides the opportunity. Comment on the veracity of the statement.

Explanation

Obviously, genes are not the only factores that determine phenotype. Environment also plays an important role in the expression of traits. Ganes are actually quite active throughout our lives, switching their expression on and off in response to the enivironment. Besides the effect of internal factors like hormons and metabolism on gene expession, external factors like temperature, light, nutrition, etc., also affect the gene expression and ultimately exhibiting phenotypic charges.
So, we can say that genes provide only the potentiality and the environment provides the opportunity for the expression of traits.
