    The effect on gene expression caused by the location of a gene within a chromosome, often due to changes in the surrounding chromatin environment.

    • Position effect can cause a gene to be silenced when it is moved near heterochromatin.
    • Scientists observed a position effect when the transgene was inserted into different chromosomal regions.
    • The study of position effects helps understand how chromatin structure regulates gene activity.
