The Siberian Husky is a medium dog, weighing between 16-27kg (35-60lbs). These dogs have strong pectoral and leg muscles, allowing them to move through dense snow. If they had heavier muscles, they would sink deeper into the snow and move slower. Yet, if they had lighter muscles, they would not be strong enough to pull sleds and equipment. This is an example of which type of natural selection? A)Directional selection B)Stabilizing selection C)Disruptive selection
Your answer is B. Directional selection is not right, because this has nothing to do with direction. Disruptive is not correct, because the dog keeps on moving, not stop because of its weight.
