HUSBANDRY
Broodstock Genetic Diversity (BGD)
Genetic variation retained in the captive lines. Falling diversity risks inbreeding and unfit rewilding stock; the cryo-bank exists to defend it.
Threshold Bands
| Band | Range | State |
|---|---|---|
| Healthy | ≥ 0.6 | OK |
| Narrowing | 0.4–0.6 | WARN |
| Bottlenecked | < 0.4 | CRIT |
Formula
Expected heterozygosity across the managed broodstock pedigree.
