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.
Can a black cow and a black bull have a white calf?
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.
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.
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.

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.
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.
Can a black cow and a black bull have a white calf?
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.
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.
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.
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 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.
