Imаgine yоu hаve discоvered а pоpulation of diploid "twinkling toads." They twinkle because of the presence of an allele at a gene called "Twink." In this population of 80 toads, 16 have two copies of the T allele and they twinkle brightly. 16 other toads twinkle a little bit, but not as brightly as the ones I just described. You can assume they are heterozygous for this gene, being Tt. There are only two alleles for this Twink gene in the population. What is the frequency of the allele "t" in this population? (Type a decimal number as your answer. If you think half (which isn't the correct answer), then you would enter "0.5")
