There are two types of hybridisation:
1) Closely related species cross and favourable traits from each are passed onto the offspring. Example Donkey X Horse breed mule
2) Members of the same species are crossed in order to get offspring with favourable traits of the parent. Example: maize- must maize in the USA in hybrids- bred with favourable traits.
• We develop on offspring that that is able to combine traits that give it a greater chance of survival and productivity, we call this Hybrid Vigour.
• Mules combine strength, endurance and ability of horses and donkeys.
