Catlin (1991) describes how he made his own strain of Creles by crossing two Crele males with two unrelated Black Breasted Red females. From the mating all the sons were dark
(intermediate) Creles and all the daughters pure Creles. By crossing first generation males and females he extracted some pure Crele males to go with the pure Crele females already obtained.

In genetic term an "intermediate" male is heterozygous for barring (Bb). Females carry but one sex chromosome so a B- female would be called hemizygous; a BB (Black Breasted) male would be homozygous for barring.
