Polled cattle are those that are born without any buds that grow into horns. Instead they have in the middle of the top of their heads a knobby area that is called a poll, thus the reason that hornless cattle are called "polled." Polled is a genetic trait that is used in a lot of cattle today, and is a trait to be taken advantage of when the offspring has a horned sire or dam.
What else can I help you with?
If a cow with horns is bred to a polled bull will her offspring be polled?
Yes, the offspring has a 50% chance of being polled. The polled gene is dominant over the horned gene, so if the bull does not carry the horned gene, the offspring will not have horns.
If a hornless bull mates with a horned cow what are the two genotypes of the two parents?
The hornless bull would have a genotype of hh, indicating it has two copies of the recessive allele for hornlessness. The horned cow would have a genotype of Hh, indicating it has one copy of the dominant allele for horns and one copy of the recessive allele for hornlessness.
Will a longhorn bull put horns on an angus?
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.
If you mate a Hereford bull with horns to a female without horns if the female is homozygous for the no horns how many calves could be born without horns Why?
All the calves would be born without horns because the gene for no horns (polled) is dominant. The female being homozygous for no horns means she carries two copies of the gene for no horns, which would be passed on to all her offspring.

Does a ram have horns?
Let's be a bit more precise: a "ram" is a male sheep, a female sheep is a "ewe" so technically there is no such thing as a "female ram". To answer the question that I think was meant to be asked is "Do female sheep (ewes) have horns?"The answer is: it depends on the breed and sometimes.Horned vs. Polled (hornless)While originally all rams had horns, sheep can have horns or not, depending upon their breed, sex, and genetics. In some sheep breeds, both sexes are horned. In some breeds, only the rams have horns. Rams usually have larger, more striking horns than ewes. When neither sex is horned, the breed is said to be polled or naturally hornless.Some sheep breeds have both a horned and polled (hornless) strain. Partial or undeveloped horns are call scurs. While horns are sometimes removed from cows or goats for safety and management ease, horns are seldom removed from sheep unless they pose a danger to the animal.
