No, twins do not actually skip a generation. That persistent family myth contains a kernel of truth, but the science tells a more interesting story. The “skipping” pattern you might notice in your family tree happens because of how the hyperovulation gene travels through generations, not because generations are mysteriously skipped. I have spent time … Read more
I first heard about the “wanderlust gene” in a travel blog that promised to explain why some people are born to explore while others prefer staying home. The article was compelling, citing scientific studies and claiming that 20% of the population carries a genetic variant that makes them inherently restless, curious, and prone to adventure. … Read more
Direct-to-consumer genetic testing companies have built entire marketing campaigns around the so-called “love gene.” They claim a simple cheek swab can reveal your capacity for empathy, your relationship compatibility, even your likelihood of being a good partner. But here is what they do not tell you: the science behind these claims is far more complicated … Read more
The APOE gene is one of the most studied genetic factors in Alzheimer’s disease research.

These two variants represent opposite ends of the Alzheimer’s risk spectrum among the three common APOE … Read more

Imagine eating a heart-healthy diet, exercising regularly, and still having dangerously high cholesterol. For millions of people worldwide, this frustrating reality stems from a single gene called PCSK9. I have spent months reviewing the research on this fascinating genetic player, and what I found could change how we think about cholesterol management forever. The PCSK9 … Read more
Genetics shapes more of Parkinson’s disease than most people realize. If you or a family member has been diagnosed, or if you are simply trying to understand your risk, two gene names keep appearing in the research: LRRK2 and GBA. These two genes account for the majority of genetically linked Parkinson’s cases. Mutations in either … Read more
If you’ve ever laid awake at night wondering if your sleep struggles run in your family, you’re not alone. I’ve spoken with countless people who tell me stories like “my mother never slept well,” “my grandmother was up until 3 AM every night,” or “everyone in my family seems to have this sleep problem.” When … Read more
Can you inherit food allergies from your parents? The answer is yes, but with an important distinction. Research shows that while you can inherit the tendency to develop food allergies, you don’t inherit specific allergies to particular foods. Twin studies suggest that approximately 80% of the risk for food allergies can be passed from parent … Read more
Is snoring genetic? Yes, snoring has a significant genetic component. Research shows that coming from a family of snorers makes you approximately three times more likely to snore yourself, with twin and family studies suggesting that 18 to 28 percent of snoring cases can be attributed to genetic factors. However, your DNA does not condemn … Read more
