1: Genetics of Elephant Tusklessness
As you watch the videos below, take notes on the following:
Purpose of tusks
Frequency of tuskless males and females
The reason the researchers think the frequency changed over time
Advantage of being tuskless
The method used to identify genes for tusklessness
Using the process of natural selection, explain the increase in tusklessness in elephants. In your response include the following:
the heritable trait and the variation (include both males and females)
Identify how inheritance plays a role in the frequency of the trait
environmental conditions affecting the trait
explain how the trait enhances survival and reproduction
frequency of the trait prior to selection and frequency of the trait after selection
You need to write well-developed responses that contain detailed information to the extent discussed in the videos, article, or textbooks. You are not required to include information that goes beyond the scope of this class.
