Document Summary

The study of the power and limits of genetic and environmental influences on behaviour. Environmental events can turn genes on which enables the gene to provide the code to make certain proteins. 22 pairs of autosomes that are the same in males and females with one pair (xx, xy) differing for sex. 96% of our genetic sequence is shared with chimpanzees. Geneticists are interested in the small variations between sequences that result in the diversity of each human. Foxp2: transcription factor that regulates gene expression during brain development, especially in motor control centres. Neanderthals had foxp2 that was the same as in humans. In songbirds, foxp2 is associated with song learning. Ke disorder: mutation of foxp2 which affects speech, mouth control and language. Identical twins: develop from a single (monozygotic) egg that splits into two. While they have the same genes, they may not have the same number of copies of these genes.
