Suppose the frequency of homozygous HbA/HbA individuals is 0.01 and the frequency of heterozygous HbA/HbS individuals is 0.18. No. NPIC is not planning to update this fact sheet. Many generations later, almost all ducks had more webbing on their feet. First discovered in 1873 by a German chemistry student named Othmar Zeidler, the compound did not receive serious attention until a 37-year-old chemist named Paul Herman Muller synthesized it again in 1936.
