Heritability of production traits is:

Barred plumage in poultry, broodiness in poultry, rapid feathering and slow feathering in poultry, cryptorchidism in horses and white eye in Drosophila are examples of:

Progeny testing and family selection are more effective when heritability of a trait is:

Inbreeding coefficients of progenies produced by selfing, parent–offspring mating, full-sib mating, and half-sib mating during the first generation are respectively:
