iology 1000 – Principles of Biology ( BioS 115 Core II: Genetics) Exam Study Guide. 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 # with the genotype Expressi...
