Instinct responsive behaviors are very stable and can last for hundreds of generations. For example in fruit flies (Drosophila melanogaster) flies that were kept in a vivarium for 80 years and never been exposed to a predator (i . e. Wasps) exhibit special reaction in terms of egg laying capacity.
How this kind of behavior exists for many many generations in lab-grown animals?
I will be glad if you can share your thoughts with me.
Instinct responsive behaviors is gene-based and control by the gene
Hello,
Of course that genes are involved in behaviour processes and in the regulation of these processes. If you are interested to find which genes are involved in a particular process (i.e egg laying behaviour) you should use the gene ontology database.
Take a look at the link below (i hope is still available) to see all known genes of D.melanogaster involved in the egg laying behaviour.
