✦ Synopsis

Two of the forms of the fruit fly, Drosophila ampelophila, which have been isolated recently by Prof. T. H. Morgan are distinguished from the normal by lesser wing length. One, called 'wingless' in Professor Morgan's papers, really possesses vestiges of wings which appear to consist largely of modified basal portions of normal wings. The other, called 'miniature,' possesses all the veins of the normal wing in approximately normal condition but the wing is only about two-thirds the normal length.

'Winglessness' is recessive to normality according to the simple Mendelian formulae. I n F1 all individuals, both W l e and female,
