It is possible to remove the anthers before they are ready to produce pollen and to cross fertilise the pea plant by bringing pollen from another plant on a paint-brush. In addition to seedpod color, flower color and flower position, the geneticist looked at the texture of seeds, seed albumen, the length of the plant stem and the form of ripe pea pods.
