Provide a genetic explanation for the origin of achromatopsia on Pingelap, and explain the most likely evolutionary model for the high frequency there of achromatopsia. Fill in the blanks with appropriate words given below to complete the sentences. Not all words will be used. 1. genetic drift 2. founder effect 3. genetic bottleneck4. inbreeding depression 5. 1/10 6. 1/20 7. 1/40 8. homozygote 9. heterozygote 10. predominant 11. eliminated The relatively high frequency of the mutant achromatopsia allele in the island population is due to created by the typhoon. After the typhoon, the allele frequency was at least , corresponding to one male among the 20 individuals surviving the storm. The mutant achromatopsia alleles of the male, along with those of the other reproducing survivors, become in the expanding population.
