While the true incidence of DSD is unknown, approximately one in every 2, live births is affected. Human gene for AMH, which is located on chromosome 19, has been cloned and sequenced 5, Winter, J.

Neither can different, local parts of a cell carry out different types of tissue specialization, such as nerve at one end and muscle at the other end.
