write in more detail about the functions of genes, about their differences from animals (duration of expression, length, etc.) (in a separate paragraph), about how and in what places (regulatory, coding, etc.) to change them, format them as a scientific work, in the text should be 5000-10000 letters

To create individuals with neko-like characteristics, several genes need to be edited in specific ways. Here is a detailed breakdown of the genes involved in shaping specific features of neko-like individuals:

Ear shaping:
- Wnt3a gene plays an essential role in the development of the spinal cord and peripheral nervous system, which affects the formation of feline-like ears in humans.

Tail shaping:
- HOXD13 gene is crucial in the development of tail-like structures at the base of the spine.

Limb and spine development:
- FGFR2 (fibroblast growth factor receptor 2) gene and FGF4 (fibroblast growth factor 4) gene contribute to bone growth in limbs and spine structures.
- SOX9 gene plays a critical role in the development of cartilage and bone, allowing for structural changes in the limbs that promote flexibility and articulation abilities.
- TBXT gene contributes to the formation of the mesoderm layer during embryonic development, which is essential for axial skeleton development.

Hair and fur pattern:
- ASIP (agouti signaling protein), MC1R (melanocortin 1 receptor), and TYRP1 (tyrosinase-related protein 1) genes are involved in the development of hair and fur patterns, which can be modified to resemble that of house cats.
- BMP2 (bone morphogenetic protein 2) gene impacts hair follicle growth and regeneration, which enables the growth of hair or fur on the tail and ears.
- EDAR gene is essential in the development of hair, teeth, and skin, allowing changes in hair type and distribution to create a fur-like coat resembling the exterior of felines.

Behavior:
- TPH2 (tryptophan hydroxylase 2) gene contributes to serotonin production in the brain, resulting in calmer and more docile behavior.

Eye appearance:
- Pax6 gene plays a crucial role in the embryonic development of the eye, including iris formation, and can be edited to produce a unique elongated pupil shape.

Skin and eye color:
- SLC45A2 gene is involved in melanin production, which can be edited to produce lighter eye and skin color.

It is important to note that editing genes for purely aesthetic purposes raises ethical concerns, and the potential impact of such modifications on individuals and the environment must be carefully considered. Conscientious use and adherence to established ethical guidelines must be followed when utilizing genetic technologies for these types of purposes.
