Abstract

The average content of o-hydroxycinnamic acid in sweetclover plants of the Cucu genotype was 36% of the level found in CuCu plants. Thus, the level of o-hydroxycinnamic acid in the F2 was more like the content of the cucu parent than that of the Cucu parent, indicating that cu was partially dominant over Cu. The calculated value for the degree of dominance of cu over Cu was +0.299. The partial dominance of the cu gene provides an explanation for the difficulty experienced in classifying plants in segregating populations.
