Gene flow is the introduction of genes/alleles between populations. An example is a flower having it´s pollen carried by a bee. The bee then introduces it (intentional or not.) to other flowers.

Risk taking has been shown to be affected at a BAL of 0.01.

At the BAL of 0.10, one's ability to think and to judge is severely affected thus making one to become prone to unnecessary risk taking behavior.
