Detachment analysis of the translocated W chromosome shows that the female-specific randomly amplified polymorphic DNA (RAPD) marker, Female-218, is derived from the second chromosome fragment region of the translocated W chromosome of the sex-limited
p(B) silkworm (Bombyx mori) strain.
Unfortunately many investigators interested in mapping ancestral states may work on similar character types: complex and/or sex-limited characters that may be subject to relatively easy loss.
Genetic drift and other factors affecting founder populations, combined with biases toward the loss of sex-limited and complex characters, likely caused repeated losses of dichromatism in ducks and other birds.
inheritance of longevity in Drosophila subobscura.
Meagher (1992) suggested that genes with sex-limited effect may respond rapidly to single-sex selection (presumably through changing allele frequencies), so that a fast change in dimorphism is possible.
Since most genes are shared by the two sexes, it is not clear how this sex-limited asymmetry could be achieved.
