Easy peasy lemon squeezy.The genetics behind Barring, Cuckoo, Lacing, Columbian, Penciling, Double Lacing, etc.
Barring- sexlinked. Mother barred father nonbarred- barred male children. Females get the non barring gene from the father.
B/B male
B/- female
Cuckoo is the same as barring but with the fast feathering gene.
Lacing takes more than one gene. It is required to have either a birchen E/E gene or a partridge e^b/e^b gene.
To keep it simple we will go Sebright style, Birchen
So E/E
Columbian Co/Co
Pattern Gene Pg/Pg
Darkbrown gene Db/Db
Melanized Ml/Ml
The full genotype for gold laced female is ERER CoCo DbDb PgPg MlMl Cha+Cha+ mh+mh+di+di+ Ig+Ig+ cb+cb+ i+i+ bl+bl+ Lav+Lav+ C+C+Mo+Mo+ b+- s+- Choc+-
Male ERER CoCo DbDb PgPg MlMl Cha+Cha+ mh+mh+di+di+ Ig+Ig+ cb+cb+ i+i+ bl+bl+ Lav+Lav+ C+C+Mo+Mo+ b+b+ s+s+ Choc+Choc+
Penciling and double lacing can have many meanings.
Partridge is controlled by the e^b gene
Double lacing is controlled by e^b and Pg genes so silver pencilled
Females are
ebeb co+co+ Cha+Cha+ mh+mh+ di+di+Ig+Ig+ cb+cb+ i+i+ bl+bl+ Lav+Lav+ C+C+ Mo+Mo+ db+db+ ml+ml+ PgPg b+- S- Choc+-
Silver pencilled males are ebeb co+co+ Cha+Cha+ mh+mh+ di+di+Ig+Ig+ cb+cb+ i+i+ bl+bl+ Lav+Lav+ C+C+ Mo+Mo+ db+db+ ml+ml+ PgPg b+b+ SS Choc+Choc+
Uh oh, this is becoming more difficult. If I need to clarify any of this raw information, just ask.
