[A statistical study of the growth and morphogenesis of axillary apparatus and notum in the Pth mutants of Drosophila].
The regularities of morphogenesis of the ventral wing-hinge structures in the Pth mutants of Drosophila melanogaster were studied using statistical methods. Our views on the vectorial growth of presumptive wing hinge as an entire unity were independently confirmed using statistical methods. The expected duplication forms, the possibility of their one-dimensional classification, the expected number of possible types, and other aspects of duplication were discussed in view of other possible suggestions on the growth of the ventral wing hinge. The growth of the anterior half of the pteropleurum was shown to have a rigid organization, because it can be described as a function of one variable. The growth was shown to be exponential. The empirical formula that fits experimental data with a significance of 99.99% was chosen. The relationship between the presumptive ventral wing hinge and the presumptive notum in respect of growth was shown to be statistical (the coefficient of correlation r = 0.37) rather than functional. Therefore, such a morphologically united formation as the wing imaginal disk does not have a unified growth pattern. The growth pattern is composed from the individual growth patterns of its constituents that have a certain degree of independence.
