The spinners, silk, etc. are all genetically determined. The behavior is the consequence of the organism’s characteristics and the environment.Given Rossums example of a spider and its web. Genes determine the physical structures of the spinner, silk, etc. But each species, once it gets its hands on the silk, has a different ‘behavior’ and spins a different pattern web.
All of them contribute to it. The genes that affect growth and size, for example, affect the size of the web and where it will be placed.What genes determine the pattern of the web the spider spins.
If one thinks that single genes determine all of such behaviors, one is probably homozygous for the gullibility gene.
