Breeders of Rare Poultry !

Genetics

Phenotype:  Derived from the word photo, it basically means what the bird appears to be visually.  

     While it is important to have a bird that looks correct to it's standard, it is even more important, if not crucial, to know what the birds genetic make-up is.  HPBAA is determined to work hard on this site to inform it's breeders, visitors, and beginners of the genetic make-up of the birds they purchase or advertise.  HPBAA will not tolerate the unknown.

Genotype:  Derived from the word gene, it means what the birds genetic make-up is.  This is the part that is unseen but important to know when breeding poultry.

     HPBAA does not claim to know genetics, but we strive to learn and study genetics to better improve the poultry we breed and represent.  This page contains contents to help it's readers strive for the same goal.
