The gene responsible for lactose persistence among adults in Europe is a regulatory gene.
The number of chromosomes does not correlate with the apparent complexity of an animal or a plant:

There are man chemical and physical changes such as geno and pheno.
I believe the answer you're looking for is Archaea-bacteria.
So dark linen thread structure is chromosome that we see. And and by molecule heritage that we contain.
