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.
What else can I help you with?
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 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.
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 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 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.
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.

In cattle coat color is codominant. Red coat and white coat. If a bull is roan what color(s) must the cow be in order to get 50 solid red offspring?
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.
Can a roan bull and a roan cow have a red and white cattle?
A roan bull and a roan cow can indeed breed to have red and white cattle. This is due to alleles mixing.
When roan color in cattle is the result of incomplete dominance between red and white color genes how would one produce a herd of pure breeding roan colored cattle?
It's simply not possible. When you breed a roan cow to a roan bull you only have a 50% chance of producing roan offspring, a 25% chance of producing white offspring and a 25% chance of producing red offspring. You have a much higher chance of producing a pure breeding red or white herd than a roan-coloured herd.
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.

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.
Do red cows and blue cows make purple cows?
No they don't. Besides, two cows that mate cannot produce offspring. Either one or the other has to be a bull, not another cow. See, cow + bull = calf. Besides, blue cattle don't exist, if you're not including the blue roan colouration. If you are, then a blue-roan cow bred to a red bull would likely produce a black calf, or even a speckled-roan calf. But never a purple calf.
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.
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.
If a red cow is mixed with a roan bull what happens?
The offspring would likely be a mix of red and roan coloring, with some variation depending on the specific genetics of the parents. Roan and red are both common coat colors for cattle, so the calf might inherit characteristics from both parents.
