The Polypay gene pool was developed from which four existing breeds?

The Polypay breed was specifically developed to combine desirable traits from various sheep breeds, particularly for use in commercial lamb production. The correct combination of breeds that contributed to the Polypay gene pool includes Finnsheep, Rambouillet, Targhee, and Dorset.

Finnsheep is known for its prolificacy and ability to produce multiple lambs, which enhances overall flock productivity. Rambouillet contributes to fleece quality and hardiness, providing wool with desirable characteristics. Targhee also has good wool traits and is recognized for its meat quality, while Dorset adds further value through its ability to breed out of season, reinforcing the Polypay's fertility and lambing frequency.

This blend of genetic traits from these four breeds offers a composite that excels in productivity, adaptability, and quality, making the Polypay a significant breed in sheep farming.
