They can be both, though historically they were primarily horned.

Yes, many Charolais are horned. Historically, all Charolais were horned. However, in today's world, there are more Charolais cattle that are polled, which is a term for being hornless.

Charbrays can be both horned or polled, or even scurred.
Charolais generally have a larger frame size, they are cream or white. However, there are breeders that have developed red and even black Charolais cattle. Bulls have distinct muscling throughout the neck, back and rump areas. They can be either horned or polled. Hair may have a little curl to it, especially in bulls.
Hornless = polled. Polled cows and bulls can be either homozygous polled or heterozygous polled. So, since we have no idea of what kind of calf they produce, the genotypical cross will look like this: (H = polled and h= horned) H_ x hh "H_" symbolizes the unknown allele that the polled bull has. Is he hetero polled or homozygous polled? The "hh" of the cow symbolizes she is homozygous horned, since the horned trait in cattle is a recessive trait: polled gene is dominant.
Amerifax cattle are predominantly polled.
Limousin cattle are both horned and polled depending on genetics. Horned tends to be more prevalent, but it is not uncommon to see French breeders that have polled Limousin cattle. Polled Limousin are most common in North America.

No. Horns are recessive-dominant, thus only appear if both parents are heterozygous polled (appear polled but have the horn gene), one is horned and the other hetero polled, or both are horned. Angus are homozygous polled, which means the first generation of offspring from a cross such as this will give you calves that are polled. They will, however, have the horn gene which means that if they are bred to a horned bull or cow, there's a much greater chance that their offspring will be horned.
