Determine the ratio of phenotypes when crossing two diheterozygotes, if the genes are not linked.

According to the third Mendel’s law, when crossing two diheterozygotes, provided that their genes are not coalesced, some signs will be distributed in a ratio of 9-3-3-1. This means that four different combinations of offspring phenotypes are possible, which were obtained by crossing two diheterozygotes.
