This week’s DNA Saturdays takes a slightly different view on DNA – What we can — and can’t — learn from our pets’ DNA: https://www.sciencenewsforstudents.org/article/what-we-can-learn-our-pets-dna-genetic-testing.
Sweetie, now 12, looks kind of like a greyhound. Or maybe a Labrador. She’s long and lean, with straight, silky fur, a happy-go-lucky face and floppy ears. Mostly, Sweetie looks like, well, a sweetie. She is a dog, after all.
DNA testing for people is very popular. But now we can also check out what genetic traits a fluffy feline or pettable pooch carries in its DNA. We can learn what breeds a pet descends from, or in what region of the world its ancestors evolved. We can even try to predict how a pet might behave or what diseases it might face some genetic risk of developing.
