In a population of cattle,the following color distribution was noted: 36% red RR ,48% roan Rr),and 16% white rr .This population is in a Hardy- Weinberg equilibrium.What will be the distribution of genotypes in the next generation if the Hardy- Weinberg assumptions are met?
A)36% red; 48% roan; 16% white
B)30% red; 60% roan; 10% white
C)30% red; 50% roan; 20% white
D)40% red; 40% roan; 20% white

In a Hardy-Weinberg equilibrium, the genotype frequencies in a population remain constant from one generation to the next if all the assumptions (no mutation, random mating, no selection, infinite population size, and no gene flow) are met. Therefore, the distribution of genotypes in the next generation will be the same as the current generation: 36% red (RR), 48% roan (Rr), and 16% white (rr).
