23 and Me: Understanding Our DNA

In contrast to different genetic checks that always require blood work, 23 and Me attracts up these experiences from a small saliva pattern that you just ship again to their lab. After six to eight weeks of processing and analyzing your saliva, you’ll obtain outcomes by way of e-mail.

Jhulianna Cintron, a product specialist at 23 and Me, says, “We consider individuals ought to have the chance to entry, perceive and profit from the human genome. That could possibly be studying about their genetic ancestry, what well being dangers they might have or discovering that their propensity for an additional cup of espresso may very well be their chromosomes.”

These DNA sequences are packaged into 23 pairs of chromosomes with directions on how our our bodies take in meals and construct muscle fibers. For each pair of chromosomes, you inherit one out of your mom and one out of your father. People principally have the identical DNA sequences, however the variations between us are variants that we inherit from our mother and father. These variants embody well being situations, bodily traits and ancestries.

“With ancestry, it’s much less about how we differ and extra about our similarities,” Cintron says. “We examine clients’ DNA to 31 reference populations from areas all over the world and search for similarities.”

My maternal grandfather suffered from Parkinson’s illness and Alzheimer’s illness, however my checks didn’t reveal any variants.
