What is the ratio of red roan white offspring from the cross of a roan bull with a white cow?

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.

What would be the offspring be if a roan cow and a white bull were bred together?
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.
Which cross will produce only horned roan offspring in cattle?
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.
What would the offspring be if 2 roan cows were crossed?
There wouldn't be any offspring. A cow cannot mate with a cow to get a calf. You must mate a cow with a BULL to get a calf. So, if the question were reworded to: "What would the offspring be if a roan cow was crossed with a roan bull?" or vice versa, then we could answer it this way: Roan colouration in Shorthorns is a codominant trait, which means that one allele is not dominant nor recessive over another. So, the resulting offspring of a roan cross would be a mix of red calves, white calves, and roan calves. The Punnet Square reveals the probability of one of three coat colours occurring in the subsequent cross: Let R = red and W = white and RW = roan. RW bull x RW cow gives us: 1 RR 2 RW 1 WW In other words, there's a 25% chance that the resulting calf would be red, a 50% chance that the resulting calf would be roan, and a 25% chance that the calf could be white.
What is the offspring of a cow and a bull called?
The offspring of a cow and a bull is called a calf. If the calf is female, she is referred to as a heifer calf. If the calf is male, then he, unless castrated after birth, is called a bull calf. Castrated calves are called steer calves.
What color will the calves be and in what proportion from a herd of white cows and a roan bull?
In a herd of Shorthorn cattle where the herdbull is roan and the cows are all white, it is probable that the resulting offspring from these crosses will yield 50% white calves and 50% roan calves.

Simmental bull crossed with hereford bull is what?
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.
What dogs create English bull terriers?
Bull terriers are a few breeds. Mainly a cross between the, now extinct, English white terrier and a bull dog.
What do you call to the offspring of bull?
Calf
What is a male cow's offspring called?
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.
In four o'clock flowers incomplete dominance appears. cross two hybrid pinks. what will be the phenotypic ratio of the offspring?
1 red 2 pink 1 white
What does a white pit bull cross brown labrador looks like?
The best advice is to keep the breed clean not breeding a pit bull with another breed.
What is a offspring of a cow and a bull called?
a calf.

A red bull when crossed with white cows always produces roan-colored offspring explain how the colors for red roan and white are inherited?
This phenomena is called incomplete dominance. Neither red nor white in this case is dominant to the other. You can also see this when breeding a Charolais (white) to an Angus (black) The offspring are kind of grey.
What do you get when you cross a pit bull with a bull terrier?
A mutt.
