🤱 "Custom Baby Selection": U.S. Company Lets Parents Pick Their Future Child's IQ and Appearance
Nucleus Genomics has launched Embryo, a service that offers genetic analysis of embryos during in vitro fertilization (IVF). The company's pitch is to help parents "optimize" their future child, assessing risks for chronic illnesses and mental health traits and even selecting characteristics such as height and IQ.
🧬 How Embryo Works
IVF clinics have been screening embryos for genetic conditions like Down syndrome for years.
What's new with Embryo is polygenic screening. Instead of looking for single gene mutations, Embryo analyzes the complete genome and calculates statistical probabilities for certain traits being expressed based on how multiple genes interact.
Parents can compare up to 20 embryos and select a few, like browsing an online catalog. One might have a lower risk of cancer, another a higher predicted IQ and green eyes, and so on.
The report includes over 900 medical conditions and more than 40 additional traits, including:
💠 chronic diseases (diabetes, cancer, high blood pressure);
💠 mental health (depression, anxiety);
💠 cognitive traits (intelligence, ADHD risk);
💠 physical features (height, eye color, hair color).
❔ Is It Effective?
Polygenic screening isn't a crystal ball; it's a set of statistical predictions. Traits like intelligence or cancer risk depend on dozens of genes and external factors such as environment or lifestyle. Many connections remain undiscovered.
The method shows probabilities, not guarantees. A child with a "low risk of anxiety" could still develop anxiety. And someone with "high IQ markers" won't automatically be a genius.
Polygenic testing is already available to adults who want to understand their health risks. Nucleus just brings that idea to the earliest possible stage—embryo selection.
