Below is some sample data that come from an imaginary class of 30 students.

Were you surprised by any aspect of this survey? Is so what surprised you? 1. Were you surprised that a trait was effected by a gene like how you interlace your fingers when you fold your hands? Explain. 2. Were you surprised that taste and flavor could be genetic? Explain. 2. Are all Dominant phenotype traits the most common trait in our population? Which dominant traits were most common? What is your evidence? 3. Are any Recessive phenotype traits the most common trait in our population? Which recessive traits were the most common? What is your evidence? 4. Dominant and Recessive does not define the frequency of a phenotype in a population. We expect recessive traits to be less common because they are only expressed if the individual is homozygous recessive. What would explain that some recessive traits are the most common phenotype in a population?
