Final answer:

The most likely mode of inheritance if the trait displayed in the pedigree is rare and completely penetrant is autosomal recessive inheritance.

Step-by-step explanation:

If the trait displayed in the pedigree is rare and completely penetrant, the most likely mode of inheritance would be autosomal recessive inheritance.

This means that the trait is caused by a recessive allele on an autosome (non-sex chromosome).

In autosomal recessive inheritance, both parents must be carriers of the trait in order for their offspring to be affected.

Offspring have a 25 percent probability of being affected and a 75 percent probability of being unaffected.
