Some information about Parent Stock and genetics behind the Phenotype of Production sex linked Brown and Silver based "Hybrids" on
Silver based Parent Stock(Both Sexes)
Genetic make up of their phenotype/
Wheaten at the e locus: eWh
Columbian Restricted: Co/Co
Dominant sex-linked Silver(S/- for females, S/S for males)
Dominant white: I/I
Not red enhanced: mh+/mh+
Brown/Red Parent Stock(Both Sexes)
Genetic make up of their phenotype/Genotype.
Wheaten at the e locus: eWh
Columbian Restricted: Co/Co
Recessive sex-linked gold(s+/- for females, s+/s+ for males)
Not dominant white (i+/i+)
Mahogany red enhanced: Mh/Mh
Terminal/Commercial sex-linked brown cross are:
Columbian Restricted: Co/Co
Recessive sex-linked gold: s+/- for females and S/s+ for males
Heterozygous dominant white: I/i+
Heterozygous Mahogany red enhanced: Mh/mh+
Terminal/Commercial Silver cross are:
Columbian Restricted: Co/Co
Sex-linked Silver: S/- for females and S/s+ for males
Heterozygous dominant white: I/i+
Heterozygous Mahogany red enhanced: Mh/mh+
Males of the both reciprocal cross will show red shoulders, lemon hackles/saddle, mostly white body due to dominant white and columbian restricted.
Isa brown rooster as example(Amberlink rooster looks the same and should have identical stats as in bodyweight and age at maturity)
Due to Mahogany the Amberlink/Silver Brown Pullets will have varying degrees of red showing on the body.
Yes, the Amberlink hen is the sister of the Isa/Dekalb brown, except is not sex linked. While doing an extensive research on reciprocal crosses like this example one can see that of the many egg production genes a few are bound to be sex linked, take this cross for example: The Amberlink is about 5% more productive than her brown sister you will hardly notice any difference in a backyard settings where both crosses will be hard press to reach 300 eggs per year, but when they are on a full production settings that 5% makes a huge difference in a flock of 1000 hens for example.
