Which breeding method may result in progeny with considerable economic value, such as the mule?
Out-crossing
Cross-breeding
Interspecific hybridisation
Inbreeding
Interspecific hybridisation involves mating animals of two different species. This breeding method can result in progeny with considerable economic value, such as the mule. The mule is produced from a cross between a female horse (mare) and a male donkey. The progeny may combine desirable features of both parents and possess traits that make them valuable for specific purposes, such as their strength, endurance, or work capabilities. Interspecific hybridisation allows for the creation of hybrids that may exhibit unique characteristics and qualities not found in either parent species, leading to their economic significance.
Option 3 is the correct answer.
