For problems involving Hardy-Weinberg equilibrium, the relative frequency of the dominant allele is usually represented by *p*, and for the recessive allele, it is represented by *q*. Moreover, the genotypic frequencies can be expressed as p^{2} for homozygous dominant, q^{2} for the homozygous recessive, and 2pq for heterozygous.

In a population of cattle, the following color distribution was noted: 36 percent red (RR), 48 percent roan (Rr), and 16 percent white (rr). Is this population in a Hardy-Weinberg equilibrium? What will be the distribution of genotypes in the next generation if the Hardy-Weinberg assumptions are met?
