Inheritance of color morphs in the meadow grasshopper

The green-brown polymorphism in Orthoptera is a prominent example of the coexistence of multiple color variants, especially since this polymorphism is shared by many species. The processes that maintain phenotypic polymorphisms depend on the underlying genetic and developmental regulation of body coloration, but these are not well understood for Orthoptera. Here we report on the inheritance of the green-brown polymorphism in the meadow grasshopper Pseudochorthippus parallelus, a species with four discrete color morphs that differ in the distribution of green coloration across the body. We provide the most detailed analysis of the green-brown polymorphism to date using half-sib full-sib breeding and phenotyping of 4,300 offspring. The data strongly support a simple Mendelian control of the presence/absence of green color in different regions of the body, involving four autosomal loci, two of which are genetically linked. However, estimation of population allele and haplotype frequencies ..., , , # Inheritance of color morphs in the meadow grasshopper *Pseudochorthippus parallelus*
