The correct answer is the visual image of a chromosomal defect.

Explanation:

An ancestral line or a chart signifying the lineage or the descent of an individual is termed as pedigree. It is depicted in the form of a diagram that demonstrates a lineage or genealogy of an organism and all its ancestors. It helps in analyzing or following the inheritance of the trait.  

On the other hand, karyotype signifies the visual look and the number of chromosomes found in the nucleus within the cells of an organism or a species. Thus, karyotype can help in determining the visual demonstration of a chromosomal defect.
