More than 10% of the variance in intelligence can be predicted by multipolygenic scores derived from GWAS of both intelligence and years of education. This accounts for more than 20% of the 50% heritability of intelligence.
The heritability of IQ for adults is between 58% and 86%. More recent studies have 80-86% heritability of IQ for adults.
Researchers have identified over 1,016 specific genes associated with intelligence and most were new intelligence related genes.
Intelligent people tend to live longer and are more likely to have autism.
Researchers at the University of Edinburgh determined that people with more intelligence genes were nearly 30 percent more likely to have genes indicating they require reading glasses.
Nature Genetics – Meta-analysis of genome-wide association studies for neuroticism in 449,484 individuals identifies novel genetic loci and pathways
Nature Genetics- Genome-wide association meta-analysis in 269,867 individuals identifies new genetic and functional links to intelligence
Selecting embryos for intelligence or using gene therapy to increase intelligence will become possible in the near future
Intelligence is associated with being richer and healthier. This will motivate embryo selection or gene therapy for more intelligence.
The maximum amount of IQ gain if screening allowed for optimal selection
Chickens have become physically larger because of breeding and farming methods
