Parkinson’s disease is a brain disorder that may be caused by mutations in several genes that code for the production of alpha-s
ynuclein. Individuals who have Parkinson’s disease exhibit symptoms such as uncontrollable tremors, difficulty walking, and loss of coordination. How might geneticists determine where the mutations that cause Parkinson’s disease are located?
Mapping and identification of the first mutations on autosomes responsible for Parkinson’s disease (PD) indisputably showed that PD may be hereditary. <span>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.</span>
This statement giving a clue that there is asexually reproduction (may be binary fission) taking place and the progenies in asexual reproduction are genetically similar to parent cell. So answer is A.
