Maternity Test Question?
Let's say a doctor examines the DNA of a mother and daughter, but does not know they are mother and daughter. Can he figure out that they are mother and daughter by looking at their DNA? In other words, is a MATERNITY TEST a specific procedure or can maternity be determined BY ACCIDENT just by looking at DNA? For example, a doctor examines blood from two victims of a crime scene. Can he determine that they are mother and daughter through his examination?

Yes, DNA matches are done by comparing alleles, which are certain markers that exist at particular locations on a DNA strand. A mother and daughter will have more alleles in common than two strangers.
I believe so. I googled "how dna testing works"
No the doctor can’t. The samples have to be sent to the DNA lab.
The technicians in the lab will find the match.
MERRY CHRISTMAS and have a nice day.
Thank you very much, while you’re up!!
You must be writing a crime novel. The DNA will show striking similarities in your scenario, but there’s no way to make that specific relationship link. A really sharp geneticist fiddling with the samples might note advanced telomere degredation in the mom’s sample and guess at the relationship with a fairly high degree of certainty, and that might give you an extra chapter or two.
