Intelligence By Praneeth Babu People normally have two copies of this chromosome. Chromosome 6 spans about 170 million base pairs, contains around1,100 to1,600 genes, and also represents between 5.5 and 6% of the total DNA in cells.This chromosome is related to the immune response, and plays a vital role in organ transplantation. A bit on the long arm of chromosome 6 has a different squence from person to person.This sequence lies in the middle of IGF2R. The chromosme needs outside influence to actually grow more intelligent. 25% of the intelligence in the long arm is developed when the baby is in the womb itself. Defects in this chromosome can cause a lot of defects, disorders, and disease, For ex: Celiac Disease, Ehlers-Danlos syndrome, Hemochromatosis, Maple Syrup Urine disease, Deafness (nonsyndromic, both autosomal dominant and recessive), Parkinson's disease, Polycystic kidney disease, Rheumatoid arthritis, Type 1 Diabetes, Epilepsy and many more.

Word: Eugenic Definition: Pertaining to or causing improvement in the offspring produced Sentence: In the heyday of eugenic IQ testing in the 1920s, there was no evidence for heritability of IQ. Pg #: 82

Some things that suprised were that the people who were trying to learn about the intelligence gene for some reason highly depended on the IQ results, they even made immigrants when they first came into America and military recruits to take IQ test just to test how genius each person is and stuff. Also they did test if twins were realted in a way that they both would have the same amount of intelligence and would get same IQ scores or atleast very similar, but once they did these trails they realized that the twins are actually less similar than ordinary siblings. Also another thing that suprised me was that Francis Galton, the guy who pioneered the study of twins to tease apart innate and acquired talents, wanted to selectively cull and breed people as they were cattle just to use as subjects.
