The failure of germination in the remaining grades may be due to degeneration of cotyledons and in the lowermost grades to the imperfectness or total lack of the embryo as well. [...] Differences in the two second backcross populations as regards the range of variability in morphological and economic characters are very probably the result of corresponding differences in the range of variability of chromosome numbers of their individual plants. [...] During the course of these investigations it was noted that in the F2 of the various crosses which happened to be both inter-racial and interspecific there was a significant excess of the hairy linted segregates from the ratios expected on the basis of the simple gene segregation. [...] (d) Modifiers of lintlessness It was noted in the early stages of this investigation that in a number of crosses involving the di fferent hairy lintless genes there was often a large deficiency of the hairy lintless class from the values normally expected on the basis of the segregation of the lintless genes alone. [...] (iii) Further evidence for the existence of the modifier action of a member of lint quantity gene complex towards disturbing the normal ratio of hairy linted and hairy lintless was available from the results of the cross between two lintless types viz.
