Respuesta :
Mapping and identification of the first mutations on autosomes responsible for Parkinson’s disease (PD) indisputably showed that PD may be hereditary. All of the currently known PD forms are dominant or recessive, which means that they are linked with regions on autosomes (chromosomes other than sex chromosomes). The chromosomes can end up rearranging and there can be a part missing of the chromosome, or it was duplicated. That can also cause PD, which geneticist can see when they look at strands of DNA.
Answer:
the answer is gene mapping
Explanation:
geneticists can use a pedigree during gene mapping to see who all had the disease
