Friends, allow me to expose some simplified points of my theoretical works related to genetics, such as types, aging, sexuality, etc.

1.- We will begin by considering two main pathways in genetic evolution, which would be the main pathway or organic pathway, and the secondary pathway or structural or chromosomal pathway.
--- The most direct or main route, or organic configuration, will be constituted by all the organelles or cellular elements that build all the architecture of the cells, and that are the organs and basic mechanisms of functioning of biology: mitochondria, ribosomes, Golgi apparatus, etc.
* By similarity with the construction of a building, these cell organelles would be all the materials with which houses are built: cement, sand, bricks, doors, windows, beams, tiles, etc.
--- The secondary pathway would be made up of construction plans, which would be the chromosomes and their genes (DNA).
These blueprints would be arranged in chromosomes, consisting of ordered packages of genes.
And precisely this arrangement and its subsequent release or perfectly ordered emission is what makes the organelles and cells repeat and proliferate properly to correctly build the body of the animal in question.
That is, the chromosomes are the body building plans, which with a correct emission of genes, are creating and building the body of the animal.

2.- Aging and sexuality.
Aging is not a direct problem of poorly constructed biology, but rather an eminently physical problem, at an atomic and molecular level.
All atoms and molecules have physical-chemical wear and tear that, if they maintain their structure indefinitely, can cause defects and accumulated defects in these molecules, especially in large macromolecules.
In other words, if the DNA macromolecules themselves are not successively recomposed and restructured, they can accumulate so many defects and defects that they would end up being useless as blueprints for biological construction, and would end up being inefficient and inadequate for their work.
So what do all these DNA macromolecules need to be healthy and sequentially rejuvenated?
Well, its recomposition and transformation with the appropriate frequency.
And that is achieved with sexuality or a method that allows splitting the DNA macromolecules, joining them with different ones, and proceeding to a reconstruction with a new structure and viability.
