He saw that the f one generation offspring always resembled one of the parents and never the other parent. Now because of this result he posed he asked the following question what exactly happens to the trait for shortness, for the short height within this offspring? Does this f one generation offspring lose the trait that gives it the shortness quality? Well, to answer that question, what he did was he took the f one generation offspring and he made it it with itself to produce the f two generation offspring. And what he saw was that although about 75% of the f two offspring were in fact tall the remaining 25 were actually short. And that meant that this tall f one generation offspring had that shore trait in it all along.
