Figure 3. An ear with twinned sectors.
The photo shows two sides of the same ear. Left-side view has a large area with parental P1-ovov454 phenotype (orange pericarp with frequent colorless sectors), while the right-side view shows a large area with typical P1-rr-Twin phenotype (dark red pericarp with few colorless sectors). A single large p1-ww-Twin sector (kernels with mostly colorless pericarp) is visible in both views. The solid purple kernels present in all the sectors result from an independent germinal reversion of the r1-m3::Ds allele and can be ignored.
