These DNA technologies identify exact familial relationships, helping scientists determine parentage and calculate kinship coefficients.
3. The Conflict: Commercial Appeal vs. Conservation Priorities
Small, captive populations are at high risk for inbreeding. Zoo geneticists use "studbooks" to track the lineage of every animal, ensuring that breeding pairs are as distantly related as possible to maintain a robust immune system and physical health.
"Nature doesn't care about our choices," Sarah said softly. "It cares about allelic richness. When you restrict a population, recessive traits like albinism—traits that are usually masked by dominant genes—float to the surface. It’s called inbreeding depression."
"And the albino male?" Elias asked.
