Traits like carcass lean meat yield and fiber diameter. You can make rapid progress just by selecting the best-performing individuals.
Reproductive traits like twinning rates or lamb survival. Because these are heavily influenced by environment/management, progress through breeding is slow. 2. Genetic Correlations: The "Package Deal" Genetic Parameters for Sheep Production Traits
Are you looking to apply these parameters to a or focusing on a particular goal like meat yield versus wool quality ? Traits like carcass lean meat yield and fiber diameter
Heritability measures how much of the variation in a trait is due to genetics rather than environment (feed, weather, management). Genetic Parameters for Sheep Production Traits
