Sinopsis
Excerpt from Defective Inheritance-Ratios in Bursa Hybrids
A defective ratio in the rosettes of one family is shown to be due to failure of dominance, and certain facts are presented, which indicate that this failure of dominance is attributable to a less relative potency of the gene A which determines the tenuis-character. This change in the relative potency of A may be due to a decline in'the efficiency of the gene itself, or to the operation of some other factor or condition which offers an increased resistance to the development of the team's-characters.

Excerpt from Defective Inheritance-Ratios in Bursa Hybrids
They seem to indicate also the presence of two genes, C and D, each of which is independently responsible for the bursa pastoris-type of capsule. The Heegeri-type appears only in the absence of both C and D. On this basis the two forms should appear in the F2 in the ratio 15: 1. The observed ratio was 1. In the F3, some families should give ratios of 3: 1, and other families should again give ratios of The observed ratios in F3 were 1, and 1. These observed ratios show a corresponding deviation from the theoretical ratios, and are thought to indicate the action of some modifying influence, such as selective elimination, distorting the results of an other wise normal Mendelian segregation.
