Unlike greys that may be born dark and lighten as it ages, a roan exhibits its coloring at birth. The Punnett Square in Figure 1 illustrates this mating. Frank needs to cross his 20 white cows (WW) with the colt-Red bull (RR). What phenotype and genotype ratios might be expected from the following matings. For this example, we will mate an Angus bull to Hereford cows. What are the phenotype and genotype ratios of the offspring when a) a roan cow and a white bull (Do Punnett Square on separate page) Genotype Ratio: Phenotype Ratio: )b)a brown cow and a roan bull (Do Punnett Square on separate page Genotype Ratio: Phenotype Ratio: 2. What phenotypes would you expect from a cross between a red bull and a white cow? In cows, the allele for red hair is H R and the allele for white hair is H W.

What is the expected phenotypic ratio if a roan cow is mated to a roan bull? Phenotypic Ratio: A RR genotype gives a red coat, Rr is roan, and rr is white. In cattle, incomplete dominance can exist in coat color. In fruit flies, humans and other mammals, sex is determined by an X-Y system. Show the Punnett Square. The Murray Grey breed was developed from an initial chance mating of a black Aberdeen Angus bull and a roan Shorthorn cow in 1905 during the Federation drought.The resulting 13 dun-grey calves from these matings were kept as curiosities and then bred on the Thologolong property along the Murray River in New South Wales by Peter and Ena Sutherland. (RR) is bred with a white cow (WW), a roan calf (RW) with red and white fur is sometimes produced. Cross a roan bull and a roan cow. A cow that has both alleles will be ROAN (spotted with red & white patches). I 10. Heterozygous The gene pair has different alleles. cattle are heterozygous for the gene for red and white, how frequently (probability. Phenotypic ratio: Same as above. The trick is to recognize when you are dealing with a question involving incomplete dominance. 16. Strawberry roan is the name for roaning over chestnut (any version of a brown color, from yellowish to reddish, all over the horse).If a roan horse has brown hairs mixed in with the white, check to see if any black hairs are present in the mane and tail, and on the lower legs. What percent of the offspring will be roan? Genotype The genetic makeup of the animal. Expert Answer 6)50% Roan bull has genotype WR and white cow has WW genotype. Again, there is no such thing as white cattle. The roan cow genotype for the blue cow happens when a purebred black cow (genotype CBCB) breeds with a purebred white cow (genotype CWCW), resulting in the genotype CBCW offspring. In shorthorn cattle, when a red bull (RR) is crossed with a white cow (WW), all the offspring are roana spotted, red and white or milky red color.
