On your house plants, you had a huge population of herbivorous spider mites with a color polymorphism. Homozygous recessive individuals are black and indicated as rr. The other allele exhibits complete dominance over the r allele. Assume the population was at Hardy–Weinberg equilibrium, with equal frequencies of the two alleles. However, then a predatory mite got into your colony, creating a population bottleneck. Only 10 individual spider mites survived: 2 red heterozygote and 8 black. However, in trying to control the spider mites, you sprayed a pesticide that killed off the predatory mite, but not the spider mites. In the absence of the predatory mites, the spider mites randomly mated and there was no evolution. Thus, within a generation, the population was back at Hardy–Weinberg equilibrium. Estimate what proportion of spider mites in your current population are red?
