A tortoise’s shell is made up of ‘â€Osteoderms†which are fused plates of bone the give the initial shell shape and rigidity. The visible layer or outer shell is made up of sectional “Scutes†which are made out of Keratin much like our finger nails. Within this Keratin are cells called Melanocytes, these cells are responsible for synthesizing pigment, thus providing a tortoise’s shell markings and coloring. Most likely an inheritable trait, but you could compare it to freckles on a human. Not any two people have the exact same layout in freckle placement or count. Although same Kin of family members and gene codes passed on will generally show in that family’s history. A perfect example of “selective breeding “for traits in breeding anything . Also a natural/evolutionary occurring event in mother nature.
Hope this helped out some ……I’m sure others can add more …….:shy:
