Genetic diversity is important for endangered species survival. Low genetic diversity increases extinction risk as populations lose their ability to adapt. This document discusses how certain endangered species like macaws, pangolins and rafflesia flowers have low genetic diversity due to poaching and habitat loss, making them vulnerable. A genetic rescue experiment introduced new genes to the inbred Florida panther population, increasing genetic diversity and allowing the population to triple in size. Maintaining genetic diversity through conservation of habitats and populations is crucial for species survival.

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?
• Plants and animals species which are in danger of Extinction are called
Endangered species.
• Endangered species with low genetic diversity may have extinction risk.

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

11. How introducing genetic variation can save
endangered species?
• Genetic Rescue Experiment
• Performed by US Fish and Wildlife Service and Researcher
team in 1995
• Example : Florida panther.

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

TEXAS MOUNTAIN LIONS:
Also called pumas
GENETIC RESCUE:
• Introduction of 8 mountain lions to
Florida Panther habitat.
• Underwent mating process
• 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.

• The panther population grew and
the next generation appeared
free of kinked tails, abnormal
reproductive organs and other
signs of inbreeding..
• 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:
Conserve Habitats
 Make space for our wildlife
 Recycle, Reuse and Reduce
 Plant native plants that are local to the area
 Control introduced plants and animals
 Join an organization

16. CONCLUSION:
• 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.
• More knowledge of complete ecosystems can help us to better understand
and protects the requirements of all life including the human species.
• Endangered means there’s still time but extinction is forever.
