Group of answer choices

linkage analysis.

Amniocentesis.

karyotype analysis.

pedigree analysis.

chorionic villi sampling.

Answer 1

Linkage analysis

Step-by-step explanation:

Linkage analysis is the only example here that does not look at possible genetic risks, such as looking for abnormal chromosome structures (karyotype) or family history (pedigree analysis).

Instead, linkage analysis is used to narrow down the chromosomal location of a particular trait. That is, it is a method used to find segments of chromosomes that harbour a particular trait.
