Explain why the phenotypic frequency of the tuskless trait is increasing in the African elephant population. Justify your answer using the vocabulary words Genetic Diversity, Polymorphic, Adaptation, Natural Selection, and fitness, the article "Tusklessness in African Elephants" and/or your phenotypic frequency calculations.

"Tusklessness in African Elephants"
Adapted from Kathleen Garigan, "Going Tuskless." © 2015 by African Wildlife
Foundation
A 2008 paper published in the African Journal of Ecology noted that the.
number of tuskless female elephants in Zambia's South Luangwa National
Park and adjacent Lupande Game Management Area had increased from
10.5 percent in 1969 to 38.2 percent in 1989-the peak of the previous ivory
wars-largely as a result of illegal hunting for ivory, A 1991 elephant
conservation plan in Uganda reported a higher-than-normal percentage of
tuskless elephants in Queen Elizabeth National Park and singled out
fitness
poaching as the main cause. Whereas a normal level of tusklessness in an
elephant population is somewhere between 3 percent and 4 percent,
according to the Ugandan report, a 1989 survey of Queen Elizabeth
National Park revealed tusklessness in the elephant population to be
between 9 percent and 25 percent.
Fact
'Elephants carry a gene for tusklessness, so in most populations there are
always some tuskless elephants," says Dr. Joyce Poole. "Because males
require tusks for fighting, tusklessness has been selected against in males
Fact
and very few males are tuskless. For African elephants, tuskless males
have a much harder time breeding and do not pass on their genes as often
as tusked males."
Adaptation
In heavily poached populations, says Poole, the ratio of tuskless animals in
the population increases as poaching continues.

Introduction

The change in the character of an organism over generations is called evolution. The evolution of organisms that improves their survivability in their chosen environment leads to natural selection.
