The gene responsible for a particular congenital cardiac anomaly is said to have complete penetrance. what are the clinical implications of this fact?

You didn't include the choices but the answer is All the individuals who possess the gene will exhibit the anomaly. The term penetrance represent the ability of a gene to express its function, with 100% or complete, penetrance, ensuring that all individuals possessing the gene will experience the phenotype in question.

What is the question? if you were looking to design a method of separating something, you can separate this compound by putting both in water and allowing the water to dissolve the sugar. then pour it into another beaker and evaporate it then boom! salt and sugar : )
