6. To obtain the F1 generation Mendel pollinated a pure-breeding tall plant with a pure breeding dwarf plant. But forgetting the F2 generation, he simply self-pollinated the tall F1 plants. Why?

Solution:

Because of true breeding, Mendel pollinated a pure-breeding tall plant with a pure-breeding dwarf plant to produce the F1 generation. Half of the kids of a genotype resemble one parent, while the other half resembles the other parent. Because the cross’s offspring are heterozygous, self-pollination is permitted.
