This paper presents a Double Kohonen Neural Network lased on the Self－Organize Feature Mapping theory to analyge chomosome automatiolly. The DKNN consists of two layers, each of which is a Kohonen network. The first layer maps a 2－d plane to a 2－d feature space to extract the high－resolution bands of chromosome and to compute the parameters of bands. The second layer maps the arrays of high dimension feature parameters to a 2－d plane to pair and classify the chromosomes automatically.
