Lets start with using letters to symbolize each allele of each parent:
Roan Bull x White Cow --> Rr x rr (where the alleles R = red and r = white).
The resulting ratio of offspring is the following:
Rr = 50%
rr = 50%
RR = 0%
Since there are too many little "r"'s and not enough big "R"'s, we can only get a cross of white and roan calves to a ratio of 1:1. Red calves do not exist in this cross.
The offspring produced is dependent on chances. We can figure out the chances of the kind of offspring such a cross will get by using a Punnett square. Unfortunately the WYSIWYG format on this site will not allow for such a square, so we will give the ratio, the genotypic and phenotypic percentages that such a cross will receive. Let R = red, W = white and RW = roan. Roan cow (RW) x White bull (WW) Offspring: 2 RW : 2 WW Genotypic ratio: 50% roan and 50% white Phenotypic ratio: Same as above. Thus, the offspring of a roan cow crossed with a white bull (presumably of the same breed, being Shorthorn), may come out as white or roan. There is a 50% chance that either will occur.
The cross that will produce only horned Roan offspring in cattle is the red bull with the white cow. However, these offspring would be able to create either red, white, or Roan.
Mating a roan bull with a roan cow typically produces offspring that can also be roan, red, or white, depending on the genetics involved. Roan coloration is a result of the interaction between two alleles, where one is dominant (roan) and the other is recessive (red or white). The expected ratio of the offspring would be approximately 25% red, 50% roan, and 25% white, based on Mendelian genetics. However, specific outcomes can vary due to the genetic makeup of the parents.
Yes, it is possible for a black cow and a black bull to have a white calf if both parents carry a recessive gene for white coloration. This would allow for the expression of the white color in their offspring.
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.

The phenotype of the offspring from a cross between a red bull and a white cow would depend on the inheritance pattern of the coat color genes. If the red coat color is dominant over the white, the offspring would likely exhibit a red phenotype. However, if the inheritance follows a codominance pattern, the offspring could display a mixed phenotype, such as roan (a mix of red and white). The specific outcome would ultimately depend on the genotypes of the parents.

Nothing, it is impossible to breed two bulls together. However, when either of these is a female the offspring would just be called a cross bred animal. A similar circumstance is when you cross a Hereford with a Charolais.
Yes, it is possible for a black cow and a black bull to have a white calf if both parents carry a recessive gene for white coloration. This would allow for the expression of the white color in their offspring.
Bull terriers are a few breeds. Mainly a cross between the, now extinct, English white terrier and a bull dog.
If a bull is roan, which is the result of having both red and white coat color genes, the cow must be solid red. This is because to produce solid red offspring, the offspring must inherit the red gene from both parents. In this case, the roan bull can pass on either a red or a white gene, but to guarantee 50% solid red offspring, the cow must only provide the red gene.
Calf
The best advice is to keep the breed clean not breeding a pit bull with another breed.
There is no such thing as a male cow. A cow is a mature female bovine that had had a calf, and a bull is an intact male bovine. So the young offspring of a bull and cow is a calf.
