I’ve never seen anything like this , and am wondering if it’s normal or some type of genetic pattern ?
Little bay roan mare of unknown breeding . She’s odd enough with her striped feet , 2 blue eyes and 4 white socks. But now she’s developing this , and no they aren’t ribs …. She’s fat lol.
Those look like ‘lines of Blaschko’. The lines are believed to trace the migration of embryonic cells.[4][5] The stripes are a type of genetic mosaicism.[6][7] They do not correspond to nervous, muscular, or lymphatic systems.

On my monitor she looks quite golden, could she be buckskin roan?
we had a red roan POA who was marked just like that
She’s cute 
!
She’s certainly Roan, with those inverted Vs on her front legs. They definitely look like the “lines of Blaschko”, which are congenital, not heritable.
Thanks everyone ! Never heard of those lines but that’s definitely what it is .
And no, she’s not very golden at all. Must just be your monitor , she’s got a red hue to her .
