HH x Hh = HH (50%) & Hh (50%)
HH x hh = Hh (100%)
Hh x Hh = HH (25%), Hh (50%), & hh (25%)
Dogs are retired as soon as they produce a better health quality pup. Such as if sires produce genetically better males, they'll retire. Similarly dams with females.
This makes it easier to organize my kennels for breeding projects and to prevent inbreeding.
