Considerable cross-breeding exists in Irish herds.
If one breeding pair exists and if that pair produces two young enough to replace the adult numbers in the next generation there is a 50-50 chance that those young will be both male or both female, whereupon the population will go extinct.
Today, a small wild breeding population exists in Mongolia.
A highly isolated breeding population exists in the Marine National Park, Gulf of Kutch, the only population remaining in western India.
Currently, no active breeding programme exists for watercress, globally, which is surprising given the important nutrient intensity of this crop relative to others.
Watercress (Nasturtium officinale R. Br). is a nutrient intense, leafy crop that is consumed raw or in soups across the globe, but for which, currently no genomic resources or breeding programme exists.
Whereas most programs have concentrated on cross-breeding, there exists a lot of potential and advantages for improvements based on within-breed selection.
Although no captive-breeding program exists within Cuba, the Centro Nacional de Areas Protegidas (the National Center for Protected Areas) has suggested it will explore this route in the future.
In animal breeding, a good example exists in breeding for improved reproductive performance in sheep in New Zealand (Young 2015), boosting lambing percentages with twins and triplets instead of mainly single lambs.
Similar cheetah breeding programs exist at four other domestic centers run by zoos.
The African gray remains popular in the pet trade, and many captive breeding programs exist.
