Alpaca Fleece-One of the hardest things to breed for

One of the hardest traits to breed for is secondary to primary ratio.
This trait has a reported heritability score of only about .20. 
The reason is that the trait is highly influenced by pre-natal nutrition. 
Secondary follicles develop during the last trimester of pregnancy with their numbers highly determined according to the female's intake of nutrition.
