Green-grain rye, when crossed with white-grain, gives green seeds in F1, and in F2 – splitting by color: 89 green seeds

Green-grain rye, when crossed with white-grain, gives green seeds in F1, and in F2 – splitting by color: 89 green seeds, 28 yellow and 39 white seeds. Determine: 1) how the seed color is inherited in rye; 2) what offspring can be expected from crossing F1 hybrids a) with a homozygous yellow-grain plant and b) with a white-grain plant.

1) The color of seeds is inherited by the type of complementary gene interaction;
2) a) from crossing F1 hybrids with a homozygous yellow-grain plant, offspring with green and yellow seeds in a ratio of 1: 1 can be expected; b) from crossing F1 hybrids with a homozygous white-grain plant, one can expect offspring with green and white seeds in a 1: 1 ratio.
