Epistemological Taxonomy: Proved Mechanics vs. Conjectured Hypotheses
| Status | Domain | Scientific Phenomenon | Mechanism / Evidence |
|---|---|---|---|
| PROVED | Cytogenetics | Triploid Meiotic Catastrophe | Odd homologous sets (3n=36) yield 98%+ unbalanced gametes in reductional division; clonal triploids universally undergo apomixis (parthenogenesis). |
| PROVED | Morphometrics | Cell Size vs. Body Size Invariance | Nuclear and cell volumes expand linearly with DNA C-value; total somatic cell count drops from ~1.45×10⁷ (2n) to ~9.67×10⁶ (3n), keeping match-head body length fixed (~3.5 mm). |
| CONJECTURED | Eco-Evolutionary | Parasite-Driven Sexual Coexistence | Red Queen co-evolution maintains sexual diploids in high-trematode lakes, while triploid clones dominate low-parasite shallow waters before ratchet decay. |
| CONJECTURED | Epigenetics | Dosage Compensation Buffering | Tetraploids (4n) show balanced quadrivalent segregation and altered metabolic gene dosage, buffering invasive tolerance in novel river habitats. |
