3 In a large herd of freely breeding cattle, the phenotypic expression of coat color are observed 200 animals. 98 of the animals are red (RR), 84 of the animals are roan (Rr) and 18 of the animals are white (rr). What is the allele frequency of the (R) allele in this sample? a. 0.6 b.0.7 c. 0.8 d. 0.9 e. 0.75 f. 0.65 b. 8 RR = 98 kr = 84 rr = 18 Ailele Frequency= P = .3 In the same population of roan cattle (98 RR, 84 Rr, 18 rr), white cattle are kept out of the mating pool for the next generation (W22= 0).
