The inheritance of a blue body color phenotype found in Cherax destructor (
the yabby) was investigated in a series of experimental crosses including b
oth F-2 and backcrosses. The blue phenotype, which can he easily distinguis
hed from the normal color phenotype in newly released juvenile yabbies, was
found to be inherited as an autosomal recessive trait. Color phenotype was
independent of age for juveniles maintained over a 12-week period. and no
association was found between color and sex. The potential for the use of t
his blue trait as a genetic marker in growth comparisons of yabby strains i
s discussed.
