Answer:
Number of albino cockroaches = 486 cockroaches
Explanation:
Assuming that the population is in Hardy-Weinberg equilibrium and that albinism is recessive, the Hardy-Weinberg equation is used to determine the frequencies ofnthe different alleles in the population
According to the Hardy-Weinberg equation : p² + 2pq + q² = 1
Also p + q = 1
Where p² is the frequency of cockroaches having similar alleles for the dominant trait;
2pq is the frequency of individuals with the heterozygous allele, while q² is the frequency of the individuals having similar allele the recessive trait, albinism.
q² = 24/666
q² = 0.036
Since, the frequency of albinism in the population 0.036, number of individuals with the recessive allele, that is albino cockroaches in the next generation is obtained by multiplying the frequency with the number of individuals in the next generation.
Number of albino cockroaches = 0.036 × 13485
Number of albino cockroaches = 486 cockroaches
