Zoo Genetics Key Aspects Of Conservation Biology Albinism -

Albinism is caused by a recessive genetic mutation that disrupts melanin production. In the wild, this is almost always a death sentence. A white rabbit in a brown forest stands out to a hawk. A pale snake cannot thermoregulate properly. Nature selects against albinism harshly.

Conservation biologists use the frequency of rare genetic anomalies (like albinism) to estimate the effective population size (Ne) of a species. If you start seeing albinos in a species that historically had none, you know the genetic diversity has crashed. It is a biological alarm bell that tells us to intervene—either by creating wildlife corridors or by genetically "rescuing" the population with translocated animals from a zoo.

In the wild, animal populations are fragmented. A species might be reduced to 200 individuals in a shrinking forest. In that tiny population, inbreeding is inevitable. Cousins mate with cousins, and rare recessive traits—like albinism—begin to surface. Albinism is caused by a recessive genetic mutation
