Pedigrees and karyotypes provide the means for individuals to identify their risks of genetic disorders. what can be evident on a karyotype but not seen on a pedigree? a. family carriers of a genetic disorder b. family history of a genetic disorder c. risk of a genetic disorder in offspring d. a visual image of a chromosomal defect.

The correct answer would be D. a visual image of a chromosomal defect.

Karyotype is defined as a visual display of the number and appearance of all the chromosome present in the cell.

It is used to detect any chromosomal abnormality such as a change in chromosome number, change in chromosome set, malformed chromosome et cetera.

it shows the family history of the genetic disorder, risk of that disorder in an offspring, et cetera.
