N normal phenotype
integument
• hairs break leading to variable degrees of baldness as mice age
• the phenotype is obvious by 4 weeks of age, especially on the back and flanks where groups of hairs are matted at tips to form clumps
• hair does not lie flat
• cuticle shown to be permeable using fluorescent markers
• abnormal distribution of S-S linkage structure inferred as causal from experiments on normal cuticle
• there is no significant difference in the lengths of the first and second hair generations
• the third hair generation was shorter than normal and likely due to friction on skin exposed by progressive hair-loss
