Human Traits Inherited characteristics
What if aliens visited our planet and thought that all humans are alike…. Are we? We are certainly different than plants or fungus!

Frequency The rate of frequency is a statistical term that helps scientists determine how often an inherited trait occurs. Frequency is important in discovering how much of the population differs (or is similar) from the whole. Frequency = Number Observed/Total Population X 100 Frequency can be used to predict evolutionary changes to environmental changes
