Dobzhansky^ has actually explained a number of the subsidiary results of the fresh new light collection away from allelomorphs in D
Oftentimes you can see that the fresh multiple negative effects of this new gene are typical of the identical nature. This is so toward attention along with and you may testis along with inside Drosophila in the list above, and with the activities to own flower colour in lot of flowers (elizabeth. But sometimes new connec- tion involving the more outcomes try anything but apparent ; for instance the grounds dumpy in the Drosophila melanogaster and this has an effect on the wings, habits out of bristle, stability, etcetera. Occasionally that set of phenotypic outcomes try brought less than one type of environment scam- dition whenever you are other standards off heat otherwise dampness, an such like. The latest plurality from outcomes of you to definitely gene could be about new instances of non-seriable multiple allelomorphs stated lower than, in which more allelomorphs belonging to the exact same locus affect various other organ assistance.
The newest generahty away from phenomena of this kind was shown of the most usual effectation of genetics into stability. Around people gene substitution inside an organism adjustment the general capacity of your ^ Gerould 1911, Rev. Ford 1937. The newest Telecommunications Out-of Genetics: The effects 163 organism growing and maintain alone, which alteration is probable an expression of your own dictate away from the latest gene overall state-of-the-art out-of reactions constituting the newest Ufe of organism. Furthermore, cells always pass away until he has got specific user of every locus; also very small inadequacies have been fatal so you’re able to tissues within the which they is actually homo- zygous.
