Two-stage Turing model for generating pigment patterns on the leopard and the jaguar
1Department of Physics, National Chung-Hsing University, 250 Guo-Kuang Road, Taichung, Taiwan.
Summary
Flecks are the earliest felid coat pattern, evolving into rosettes and blotches. A Turing model simulates this, generating leopard and jaguar patterns from initial spots.
Area of Science:
- Developmental biology
- Evolutionary biology
- Mathematical modeling
Background:
- Felid coat patterns exhibit diverse markings like spots, rosettes, and blotches.
- Understanding the evolutionary origins and developmental mechanisms of these patterns is crucial.
Purpose of the Study:
- To investigate the evolutionary origin of felid coat patterns.
- To model the development of diverse felid coat patterns using a reaction-diffusion system.
Main Methods:
- Phylogenetic analysis to determine the ancestral coat pattern.
- Construction of a Turing reaction-diffusion model to simulate pattern formation.
- Parameter tuning to generate specific felid coat patterns.
Main Results:
- Phylogenetic analysis indicates flecks are the primitive felid pattern.
- The Turing model successfully generated initial spot patterns.
- Parameter adjustments allowed the model to replicate adult leopard and jaguar patterns.
Conclusions:
- Coat pattern evolution in felids likely proceeded from simple flecks to more complex markings.
- Turing reaction-diffusion models can effectively simulate the development of diverse animal coat patterns.

01:39Epistasis
In addition to multiple alleles at the same locus influencing traits, numerous genes or alleles at different locations may interact and influence phenotypes in a phenomenon called epistasis. For example, rabbit fur can be black or brown depending on whether the animal is homozygous dominant or heterozygous at a TYRP1 locus. However, if the rabbit is also homozygous recessive at a locus on the tyrosinase gene (TYR), it will have an unshaded coat that appears white, regardless of its TYRP1...
02:19Morphogenesis
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.
