If a cell is fused with another cell, which of the following would be the best example of a trans-mechanism of epigenetic control?
A) A gene that is originally silenced in one cell but expressed in the other is silenced in the hybrid
B) A gene that is originally silenced in one cell but expressed in the other is still expressed in the hybrid.
C) The methylation pattern of the same gene from either cell is not altered
D) There are no examples that could conform to a trans-mechanism

In a trans-mechanism of epigenetic control, factors from one cell can influence the gene expression of another. If a gene is silenced in one cell and remains silenced in the hybrid, it suggests that silencing factors from the first cell are acting in trans to silence the gene in the hybrid.
