Biology 1000 – Principles of Biology ( BioS 115 Core II: Genetics) Exam Study Guide Questions With Answers. Explain the concepts of penetrance and expressivity 
Penetrance is the percentage of cases in which a certain phenotype is expressed. There 
are two types: 
i. Complete Penetrance: when 100% is correlated to the genotype. So, all express 
the same thing. 
ii. Incomplete: this is when some are identical, and others are different. 
Penetrance= # with genotype showing phenotype x 100
