The "genuine" medicine is patented and protected until the patent expires, then other companies can prepare generic versions. There may be differences in the inert fill, dose and method of delivery (pill, capsule, etc.) but the basic active medication was approved (by the FDA, etc.). Generic medications still need a doctor's prescription although weaker doses may be allowed in OTC (Over the counter non-prescription versions if allowed (by the FDA).
They are SUPPOSED to be identical. However, some medicines seem to have binders/fillers that change the absorption. When it is really essential that the physician know how a med is going to work, he insists on the brand name. In my field, for example, the difference between Dilantin,( brand name) and Phenytoin ( generic) can be significant. I have had well controlled seizure patients go out of control just by changing from brand name to a generic.

Genuine medicines are given only on doctors prescription; generic medicines are freely available and also appear in advertisements.
