Treehouses are built on the stem and the three branches, which do not grow in length, only in width. Trees grow in length only in the area of the buds, which are located at the ends of branches.
Maybe it is easier to understand this if you imagine that you put a small house replica on the palm of your hand and that your fingers are constantly growing from their tips. So, the house on your palm would not move, only your fingers, (the analogy to the three top buds) would become longer.

Explanation:
Dominant alleles are always expressed when they are present. Recessive alleles are masked by dominant alleles.
Therefore, two copies of a recessive allele are required to show the recessive trait. Either one or two copies of a dominant allele produces the dominant trait.
