The following is a description of allelic frequency. Read the passage carefully and then write your answer.
In cattle, roan is a pattern of red and white which is the most prevalent. There are only a few red
cows and only a few white cows. On a sheet of scratch paper develop a frequency distribution chart
that shows this. Now read the following scenarios and decide what kind of shift has happened with
the allelic frequency.
Scenario 2
Mr. Huckle, goes to the market one day. While he is out, a pack of coyotes ravage his farm. The
coyotes believed that the roan cows taste better, so those are the ones they choose to eat, leaving
the white cows and the red cows to look on in fear. Describe the allelic frequency distribution in this
scenario.
