Creeping clover (T. repens) has plants with high and low cyanide content. Cyanides increase the activity of protease, amylase and other enzymes, as a result of which the vegetative mass of plants increases, their feed value improves. Genetic analysis shows that the inheritance of a high cyanide content is due to the complementary interaction of the dominant alleles of the two genes L and H. Cyanide in clover leaves is formed from the glycoside linamarin under the influence of the enzyme linamarase. The H gene provides for the synthesis of linamarin, and the L gene provides for the linamarase enzyme. In the absence of one of these dominant genes in the genotype, the plants are characterized by a low cyanide content. Determine what offspring can be expected from crossing plants with genotypes (females) LIhh and (male) 1IHh.
Plants with low to high cyanide content in a 3: 1 ratio.
