Question

difference between penetrance and expressivity

Answer 1

Penetrance: is the percentage of individuals with a dominant allele that also exhibit the dominant phenotype
 
Expressivity: is the extent to which a trait or condition is expressed. In other words, expressivity refers to how mild or severe the phenotype is and which of the hallmarks of the condition are present. 

Answer 2

Answer:

The main difference between penetrance and expressivity is that penetrance is a quantitative measurement, describing the levels of expression of a particular phenotype, which corresponds to a dominant genotype whereas expressivity is the extent of a given genotype expressed at the phenotypic level.
