Some deer have horns while other do not, primarily because of gender. A deer's gender may influence the fact that it has horns or not, because most male deer fight.

There are many animals hunted for their horns: Elephant (if you count a tusk as a horn), Rhino, some sheep and goats, deer breeds are also hunted for horns. These are just a few but there are others that are hunted for horns. If they have a horn then they are most likely to be hunted for them - unfortunately
There are two main types of cow horns: twisted horns and straight horns. Twisted horns are curved and spiral-shaped, while straight horns are, well, straight. The size and shape of cow horns can vary depending on the breed of cow. Some cows have long, wide horns, while others have shorter, narrower horns. Overall, the size and shape of cow horns are determined by genetics and can vary greatly between individual cows.
HORNS AND SKIN: some people decorate their interior of their houses with deer's horns and skin
Some do, others can be polled as well.
The animal with the largest horns is the African buffalo, also known as the Cape buffalo. Male African buffalo can have horns that span up to 2 meters (6.5 feet) wide. These horns are used for defense and dominance displays within the herd.
The white tailed deer is the only animal that sheds their horns each year. This makes the size of the horns of some specimens remarkable, because they have grown in one season.
Chameleons that are female usually grow minimal no no horns, while some species do grow horns.
Goats are related to sheep for obvious reasons such as hoofs and horns, tails and fur (wool) but some think they are related to deer (more than they are to sheep) because deer have the same tail and they grow horns and they also have hooves while sheep have wool and deer have fur but goats don't have wool they have fur. Goats could also be related to horses through the hooves gene but that would be a short scientific reason why. We all originate from something!

No cattle have antlers. They have horns. You could be thinking of moose or elk, which are part of the deer family and have antlers.
in some species female chameleons grow minimal horns or no horns at all. some females horns are 12-14 inches long while males can grow up to 14 inches long
