has_sequence_attribute has_staining_intensity Used to link a gross chromosomal sequence feature (chromosome part) to a color value quality that inheres in the sequence feature in virtue of the staining pattern of the chromosomal DNA in which the sequence is materialized. Consider obsoleting - it is likely sufficeint to use the parent has_sequence_attribute property - a separate proeprty to link to the staining intensity attribute is not really needed. has_color_value
