Answer:
<em>If crossing over did not occur there would be no diversity among organisms.</em>
Explanation:
Crossing over and independent assortment are the two phenomena of meiosis by which genetic and physical diversity occurs. If crossing over did not occur then there would not be changes in the physical features of children. No physical diversity would be produced. Children would have the same physical features as the parents. Each chromosome would be identical to one of the parents and hence there will be reduced variations.
They are like the animals who fly. They do have built-in mechanisms that enable them to go up and down in the water. The downward pull is the gravity and the upward push of the buoyancy. The force of the buoyancy is equal to the weight of the fluid displaced by that object. So fishes use their swim bladder for them to be able to ascend.
