What did the statistician and geneticist Ronald Fisher observe about Mendel’s research?
In 1936 Ronald Fisher published a statisti- cal analysis of Mendel’s data concluding that “the data of most, if not all, of the experiments have been falsified so as to agree closely with Mendel’s expectations” The accusation gave rise to a controversy which has reached the present time

What are hypotheses?
A hypothesis is an assumption, an idea that is proposed for the sake of argument so that it can be tested to see if it might be true In non-scientific use, however, hypothesis and theory are often used interchangeably to mean simply an idea, speculation, or hunch, with theory being the more common choice
