When two white-grain corn plants were crossed, F1 was also white-grain, and in F2, 132 white and 29 purple seeds were obtained. Determine: 1) the nature of color inheritance; 2) genotypes of plants with purple color of seeds.
1) Coloring of seeds is inherited by the type of epistatic gene interaction;
2) if the gene that controls seed color is designated as A, and the epistatic gene is designated as B, then the genotypes of plants with purple seeds are AAbb or Aabb.
