Resumo
O Modelo Mosaico de Clones
apresentou um método de
síntese de padrões de pelagem
animais, como girafa e grandes
felinos,
diretamente
na
superfície
do
objeto,
considerando as mudanças
dinâmicas na forma. Neste
trabalho, nós estudamos a
viabilidade do MClone na
síntese de padrões vegetais,
especialmente na melancia
como estudo de caso.
The Clonal Mosaic Model
The model assumes that the coat patterns for
some mammals represent a spatial arrangement of
epithelial cells - a Mosaic - where all pattern
elements are derived from a single mother cell,
and are therefore clones.
Among the many properties, the 3 most important
ones are: Division Rate, Adhesion and Mutation.
The figure shows that when we increase the
adhesion between cells of the same type, we have
more spots defined on the surface. If we move
away from the origin in the adhesion axis, the
object will change from a granular appearance to
consistent spots. Moving from the origin in the
probability axis, there are more black spots. We
assess that the last column to the right in the
figure shows the best results.

Biological Background
The BW pattern is due to a type of
mutation called White Spotting,
where the death of melanocytes - cells
that produce the coat color pigment
called melanin - cause white and
irregular patches in the coat of the
animal. The melanocytes originate in
the neural crest and migrate over the
animal’s body during embryonic
development.
