Many polygenic traits are represented by a bell cure because they are controlled by many genes and result in gradations where each gene has an effect.
An increase in demand is represented by a shift of the demand curve to the right; not a movement along the demand curve. An increase in the quantity demanded would be a movement down the demand curve.
oligopoly
Shift of the curve to the left.
Graphic are represented using geometrical primitives such as lines, points, curve, shapes or polygons.
by a shift to the right of the demand curve
It would not shift the curve; it would be represented by moving from a point inside the curve toward the curve.
...trait shows continuous variation in the population with most individuals clustering around the average value, and fewer individuals at the extremes. This pattern results from the combined effects of multiple genes influencing the trait, along with environmental factors.
An increase in quantity supplied is represented by demand.

"Multiple points in a curve" typically refers to locations along a curve where certain conditions or characteristics are met simultaneously. For example, in mathematical terms, it may indicate points where the curve intersects itself or has the same y-value for different x-values. In a broader context, it could also refer to various significant features along the curve, such as peaks, troughs, or inflection points, which provide insight into the behavior of the function represented by the curve.
That would depend on what point of the curve you mean.
