2. WHAT IS GENETIC DIVERSITY?
The variety of genes or inheritable characteristics present
in a population.

3. What are endangered species and its relation with
genetic diversity?
โข Plants and animals species which are in danger of Extinction are called
Endangered species.
โข Endangered species with low genetic diversity may have extinction risk.

5. โImportance of genetic diversity in endangered
speciesโ
โข Allow individuals to adapt different changes.
โข High genetic diversity increases ability of
populations and
species to survive major changes in their environment.
โข High genetic diversity avoid inbreeding or disease epidemics.

endangered species?
โข Genetic Rescue Experiment

12. FLORIDA PANTHER
โข Declining population (12-20)
โข Inbreeding depression
โข Abnormal reproductive
organ development
โข Kinked tails and low sperm
counts.

TEXAS MOUNTAIN LIONS:
Also called pumas
GENETIC RESCUE:
โข Introduction of 8 mountain lions to
Florida Panther habitat.
โข Underwent mating process
โข The new panthers brought with them
new gene versions, which help
counteract two negative side effects of
small population size: reduced genetic
variation and inbreeding.

โข The panther population grew and
the next generation appeared
free of kinked tails, abnormal
reproductive organs and other
signs of inbreeding..
โข Now, the population size has
tripled and over the past 30 years,
the panthers have gotten a
further boost from increased
legal protection

15. OtherWays you can help endangered species:
๏ฑConserve Habitats
๏ฑ Make space for our wildlife
๏ฑ Recycle, Reuse and Reduce
๏ฑ Plant native plants that are local to the area
๏ฑ Control introduced plants and animals
๏ฑ Join an organization

16. CONCLUSION:
โข Our national heritage of biological diversity is an invaluable and irreplaceable
resource.Our quality of life and that of future generations depends on our
preservation of plants and animals species.
โข More knowledge of complete ecosystems can help us to better understand
and protects the requirements of all life including the human species.
โข Endangered means thereโs still time but extinction is forever.
โ Each and every animal on earth has as much right to be here as
you and meโ
