Low Genetic Diversity in Snow Leopards

October 19 , 2025 6 days 79 0
  • A new study by Stanford University found that snow leopards have the lowest genetic diversity of any big cat, even lower than cheetahs.
  • Researchers attribute the low genetic diversity to a historically small population size rather than recent inbreeding.
  • Snow leopards show effective purging of harmful mutations, maintaining health despite low genetic variation.
  • The species has significantly less harmful homozygous gene load compared to other Panthera species.
  • The global wild population is estimated between 4,500 and 7,500 individuals across 12 Asian countries.
  • In India, 718 snow leopards were estimated in a recent survey, with Ladakh hosting the highest number at 477.
  • India holds the third-largest population of snow leopards globally, after China and Mongolia.
