User:Quercus solaris/Genetic information and resultant peptide collections that "come in group packages"

They "come in group packages"—but not always as the *proximal* result of natural selection (and the *proximal* results thereof are what people usually tend to think of as the sole driver of heredity); rather, as a *distal* result several abstraction layers removed (but easily just as influential, although it is much harder for humans to see the causative mechanism behind the influence). Still with a concrete result, of course—a concrete linkage—but not by the most simplistic mechanism.

Somehow one should be able to write simple sentences about the ontology of the following:

• sequence motifs
• conserved sequences
• supergenes (gene complexes)
• protein domains
• structural motifs

What else belongs on this list? Probably at least a few other topics.

Updates: Later, the following suggested themselves:

• The more obvious ones:
  • sequence homology
  • protein family
  • protein superfamily
  • gene family
  • gene cluster
  • genetic linkage
• The less obvious ones:
  • pleiotropy, which has more to do with the theme of this discussion than most people might think it does on the surface
    • whole genome sequencing and artificial intelligence, which have more to do with the analysis and appreciation of pleiotropy than most people might think they do on the surface—WGS to find out "what's there", and AI to figure out "what significance it has" and perhaps even "why it's there"
  • copy number variation
  • gene dosage
    • dosage compensation
      • X-inactivation
  • genetic drift
  • genetic draft (genetic hitchhiking)
  • selective sweep
  • background selection
  • overlapping genes
  • unit of selection
  • niche construction (the ironing is delicious)
