High rates of
volcanism, earthquakes, and mountain building are the sites of subduction
zones. They occur in convergent boundaries found in tectonic plates of both
oceanic and continental crusts. Subduction zones occur when one tectonic plate
moves under another tectonic plate, sinking into the mantle as the plates
converge again.

Regions that are
within subduction zones experience an average rate of convergence of 2-8
centimeters per year. They are subject to many earthquakes because of the
collisions that occur within the tectonic plates. </span>
Answer: Option B - There are more than four genes that determine this trait.
Explanation:
The tobacco plant species have its leaf colour with characteristics that changes gradually over a range of values, which refers to continuous variation.
Note that continuous variation keep expressing gene variants in successive generations of the tobacco plants, that differs from the parents. So, there are MORE THAN four genes controling the expression of varying phenotypes in the leaves
