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 RR = 98 kr = 84 rr = 18 b. 8 c. 13 d. 11 e. 4 f. 16 84 R allers = 2x 98 x 84 = 280 ralleles = 2x 18 x 84 = 120 Total alleres = 400 2pm 110 AR alleles = 280/400 = -7 7 = 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). How many white cattle (approximately) would be expected after this type of selection in a new population of 200 cattle? a. 2
