tested

and reproduce most successfully
A well-supported, testable explanation of phenomena
observed in the natural world
A small population of 250 Saint Lucian parrots lives in
the small rain forests of the Caribbean island of Saint
Lucia. The parrots never leave the island, and parrots
from neighboring islands do not come to Saint Lucia.
The parrots live in three rain forest areas, but parrots
from all the regions freely mate with parrots from
other regions. The appearance and characteristics of
the parrots have remained the same for generations
without variation. Analyze the description of Saint
Lucian parrots and identify the conditions and
violations of the Hardy-Weinberg rinciple that apply
to the parrot population.
