The primary objective of this study was to determine the frequency distributions of certain quantitatively inherited characters in F2 populations of crosses between homozygous lines of corn, and to attempt an interpretation of these distributions with regard to the nature and action of the genes concerned.

Three inbred lines, Ind, Wf9, Ind. 38-11, and Sg 30A, and the two F1 single crosses Wf9 x 38-11 and Wf9 x 30A and their F2 populations were grown for this study.All three lines have been inbred for at least seven years and are considered to be reasonably homozygous.

Individual plant measurements were taken for the following seven quantitative characters: days from planting to pollen shedding, plant height, circumference of stalk, ear length, ear diameter, number of kernel rows, and ear weight.
