CRISPR Babies and HIV Resistance

Did you know that some people are resistant to HIV? People who carry two copies of the CCR5 delta-32 mutation are resistant to *most* strains of HIV. (Still not something to test out!) Check your genes to see if you carry this mutation.

Are you genetically more likely to have twins?

Twins tend to ‘run in families’, which is a colloquial way of saying that there is a hereditary component that increases the likelihood of having twins. Check your genetic data (women only :-) to see if you are more likely to have twins.

Genetics of Red Hair

To have red hair, you need to carry two variants in the MC1R gene. We all know our hair color, but it turns out that if you carry one MC1R genetic variant (and don’t have red hair) you are still at an increased risk for skin cancer.

Lactose Intolerance Genes

Your genes control whether you are likely to produce lactase as an adult. Check your 23andMe or other genetic data to see if you are likely to enjoy a big glass of milk.
