Mating of an organism to a double recessive in order to determine whether it is homozygous or heterozygous for a character under consideration, is called

Find out the percentage of dominant phenotype in cross between $P_p$ and $P_p$. $P-$dominant, $p-$recessive

In wheat, when a green plant was self-fertilized, the progeny had $209$ green seedlings and $14$ white seedings. The above result indicates that
