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?
The calves can be a combination of white and roan. Since roan is a dominant color pattern, the majority of the calves are likely to be roan with white markings. The exact proportion of each color will depend on the genetics of the animals involved.

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?
To produce a herd of pure breeding roan colored cattle, you would need to continuously breed individuals that exhibit the roan phenotype, as this indicates they carry one copy of the red and one copy of the white gene. By selecting for this phenotype in each generation and avoiding mating individuals that are homozygous for either red or white, you can establish a herd of pure breeding roan cattle over time.

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.

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.
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 color will the calves be and in what proportion from a herd of white cows and a roan bull?
The calves can be a combination of white and roan. Since roan is a dominant color pattern, the majority of the calves are likely to be roan with white markings. The exact proportion of each color will depend on the genetics of the animals involved.
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.
1. Cattle can be red (CCR) and white (CWCW) and produces a roan color(CRCW) of offspring,a.) Predict the genotypic ratios of offspring if two roan color cattle arecrossedb.) What are the possible phenotypes of the offspring?
Pls answer this😭
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.
What color foal should you have between a blueroan horse and chestnut?
A true blue roan is a black horse with the roan gene. In order for the horse to be black it has to be aa at the agouti site and either Ee or EE at the extension site. aaEeRn- or aaEERn- the second allele at the roan site is unknown. The chestnut horse has to be ee at the extention site. Unfortunately, without some knowledge of the colors of the parents of both these horses it will be difficult to determine the probability of color. We do know that there is a minimum of a 50% chance that any foal produced will be roan. (If both parents of the roan are roans themselves there is a potential for the roan horse to be RnRn.) If the roan parent is RnRn any foal produced from this mating would be roan. We also know that, if the blue roan is Ee at the extension site there is a 50% chance that any foal produced will be chestnut (whether with or without roaning). (If either of the blue roan's parents were chestnut we would know that the roan parent is Ee.) We know that the blue roan is aa at the Agouti site, but without further study of the chestnut's parents, grand parents and her and their offspring it would be difficult to know if the mating could produce a Bay (A). If the chestnut parent is Aaee 50% of the non chestnut foals will be Bay and 50% will be black. Hope this helps.
