Expressivity
From WikiLectures
The different nature (degree of disability) of the already manifested hereditary trait in the carrier, corresponding to the given genotype.
Expressivity depends on many factors:
- other genes,
- environmental influence
In carriers of the same dominant allele, we find a spectrum of morphological deviations (example: polydactyly - from skin folds to multiple functional fingers).
It describes the degree of expression of the given genotype in the phenotype.
