"Polled his hair" typically refers to the act of cutting or trimming hair very short, often to the point of shaving the head or creating a uniform length. The term "poll" in this context is an old word that means to cut or trim. It can also imply a transformation in appearance, often associated with a specific style or look.
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?
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.
What does polled mean for a sheep?
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.
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?
This is not a matter of how many it's a matter of chance in terms of percentages. In this example, any bull that is horned is ONLY homozygous, both phenotypically AND genotypically, for horned because the horned gene in cattle is recessive. The polled (non-horned) characteristic in cattle is a dominant trait both phenotypically and genotypically. So that means that any horned parent that breeds a homozygous polled parent will have offspring that are ALL polled. The only way you will get horned offspring is one of two ways: a horned sire mates with a horned dam, or, a hetero polled sire mates with a hetero polled dam (resulting in a much smaller chance than the first way). The question above is answered as followed:Homozygous Horned (Hereford) bull x Homozygous Polled female = 100% Polled offspring.I cannot use the Punnett square on this site, but if you use it on a piece of paper you will see that 100% of all offspring are polled. But notice that genotypically they are HETEROZYGOUSLY polled. This means they are polled physically, but in their genes their offspring have a 50% chance, should this offspring be bred to a horned partner, of having either horned offspring or polled offspring. If the offspring of the above cross were bred to a polled partner, the results would be 50% hetero polled and 50% homozygously polled. AND, if the above offspring were bred also to a hetero polled partner, you would get, phenotypically, 75% polled and 25% horned. Genotypically, this is 25% homozygously polled, 50% hetero polled, and 25% homozygously horned.See, the most a cow can have in her lifetime is 20 calves. There is no way that she can have 100 or so calves in her lifetime to see this example work out. Producers have to go by chances of an event happening when selectively breeding cattle, not how many.

What breeds of cows are polled?

Are jersey cattle polled or horned?
Amerifax cattle are predominantly polled.
Are senepol cattle horned or polled?
Polled. The dominant polled characteristics come from the Red Poll breed that is infused into this breed to make it the Senepol breed.
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.
Are char bray cattle polled or horned?
Charbrays can be both horned or polled, or even scurred.
Polled is when a cow or goat is born and never grows horns?
Correct. "Polled" is the term given to cattle and goats that never grow horns. For example, Red Polls and Angus are cattle breeds that are naturally polled. Appenzells are a naturally polled breed of goats.
If a hornless bull mates with a horned cow what are the two genotypes of the two parents?
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.
