Forest rangers are genetically testing the deer in the forest after many were found dead. The tests determined that due to inbreeding, most deer have a genetic disease which decreases life expectancy. Based on genetic and mortality data, the rangers predict that the population of deer will be gone in 3 years. What initial concerns do the rangers most likely have?
