Having extra fingers (polydactyly) is a dominant trait. Having just 10 fingers is a recessive trait. How can you explain that almost (if not everyone) you know has the “normal” number of fingers? Look at the list of dominant vs recessive genes and give another example of a recessive gene being more common than a dominant one and explain why you think that dominance or recessiveness is not related to how often a trait occurs in a population
