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 1
Mr. Huckle, the farm owner is very superstitious. He thinks the roan cattle are bad luck. Last time he
butchered roan cattle and sent the meat to the market, everyone in town got sick. He now prefers to
butcher only the solid colored cows and sell their meat instead. Name the kind of distribution this
would result in.
