The x and y (horizontal) axes indicate values of two different traits The height of the peaks indicate the fitness of a particular trait combination Natural selection will tend to lead a population "uphill" from their starting position The shape of the fitness landscape stays the same regardless of the environmental conditions

Answer 1

The shape of the fitness landscape will change according to the environmental conditions. So the 4th option is the wrong one. Different trait combinations suitable to the given environment conditions of the place will result in a higher peak, while negative environment conditions will result in a lower peak.

The x and y axis indicates different traits,whose ideal combination will result in a higher fitness rate,hence higher chances of survival and therefore a higher peak.

The height of the peak represent the fitness of a particular trait combination. A higher peak represents better fitness and better chances for survival.

Naturally selected species does have a higher chance of survival. Therefore their fitness curve have chances to move uphill.
