Genetic complementation analysis

Four pure-breeding white flower mutants (A–D) are crossed in three crosses (1–3) to test genetic  complementation. Cross 1 shows genetic  complementation, whereas Crosses 2 and 3 do not.Four pure-breeding white flower mutants (A–D) are crossed in three crosses (1–3) to test genetic  complementation.
