When mendel crosses a tall plant and a short plant the f1 generation that resulted were all tall. when he allowed the f1 generation to self pollinate then __ generation that resulted we’re 75% tall and 25% short

F2 Generation.

Explanation:

After Mendel collected seeds from the F1 plants, he set them to soil and waited for the F2 generation to grow from them. In the F2 generation, out of the 1064 plants, 787 were tall and 277 were dwarf. And that is roughly three quarter were tall and one quarter were dwarf, giving a ratio of approximately 3:1.

At this point, Mendel called dwarfness a recessive because it has receded in the F1 generation only to appear in the F2 generation and that of tallness was termed to be dominant in the pea crossing experiment of Mendel.
