In Addam's family, there is an autosomal dominant condition in which webbing attaches the second toe to the third toe and the second toe is longer than the big toe. Only some of the members who have inherited the mutant allele have a second toe longer than the big toe. In addition, the extent of webbing varies. This phenotype is Select one:

a. Variably expressive and incompletely penetrant
b. Dominant and recessive
c. Invariably expressive and completely penetrant
d. Both inherited and non-inherited

A. Variably expressive and incompletely penetrant

Explanation:

Incompletely penetrant is a genetic term which means the genetic trait is visible in a fraction of people.

Variable expressivity is the range of signs and symptoms developed in different people with the same genetic condition.

Only some of the members who have inherited the mutant allele have a second toe longer than the big toe signifies variably expressive trait while the extent of webbing varying signifies incomplete penetrant.
