• sires mated with a/a dams, but not dams mated with a/a sires, that were supplemented with methyl donors ((folate, choline, betaine, vitamin B12, zinc, and methionine) during pregnancy show a significant shift in the spectrum of color phenotypes toward pseudoagouti, indicating that in utero methyl donor supplementation affects the somatic epigenetic state of the Avy allele only when the allele is derived from the male
• F1 pseudoagouti females that had been exposed to methyl donors in utero from E8.5 to E15.5 and mated to a/a males without further methyl donor supplementation, produce offspring (F2) showing a sift toward pseudoagouti coloration, indicating that diet/environment has an enduring influence on succeeding generations, independent of later changes in diet

|
• the ventral hairs are substantially less pigmented than those of the dorsum
|
|
• although in early stages of hair growth the granules are round and relatively uniform in size, in later stages they are larger, more variable in size, and some clumping is found
• by the 9th day of a new hair growth cycle some hair bulbs are devoid of pigmentation and by 14 days very few follicles have active melanocytes
|
|
• variation in the amount of pigmentation present in one hair shaft versus the next
• variation in the size ans shape of pigment granules, with some instances of large masses of pigment in a particular hair shaft
|
|
• hair shafts have large clumps of pigmented granules predominantly restricted to the medullary regions
• decreased pigmentation in the hair shafts with age
