What does expressivity refer to?
The degree to which a phenotype is expressed, varying from mild to severe
What is the term used to describe the masking of the expression of one gene by another?
Epistasis
What do temperature-sensitive alleles like the Himalayan allele in rabbits exhibit?
Varying expressivity based on the environment
Which term refers to a functional enzyme or protein being produced?
Wildtype allele
What is the main difference between penetrance and expressivity?
Penetrance varies among individuals, while expressivity varies within an individual.
