N normal phenotype
pigmentation
• agouti pattern is modified, the entire coat being unusually dark
• due to abnormal hair growth exposing lower non-agouti hair shaft

integument
• agouti pattern is modified, the entire coat being unusually dark
• due to abnormal hair growth exposing lower non-agouti hair shaft
• the first coat develops a little more slowly than normal
• absence of auchene and zigzag hairs results in a coat with a thin, ragged appearance
• nearly absent
• growth of the late differentiating hair follicles which produce auchenes and zigzags is very retarded or arrested

homeostasis/metabolism
• Background Sensitivity: two large group studies on different mixed background showed the frequency of ascites to be 11.1% and 17.8%
