Question

Mule is a offspring of
A. Cross breeding
B. Interspecific hybridisation
C. Intraspecific hybridisation
D. None of the above

Answer 1

Hint: A mule is the offspring of a female horse and a male donkey. A mule is simpler to procure from the two first generation crosses of these two animals than a hinny, which is the offspring of a female donkey and a male horse.

Complete step by step answer: Cross breeding is the breeding method with the goal of developing offspring that bear the characteristics of both parent lineages or creating an animal with hybrid vigour.
Hybridization among different sub-species within a species is intraspecific hybridization.
Interspecific hybrids are bred from two species by mating individuals, usually from within the same genus. The offspring bear both parents traits and features, but are always sterile, eliminating gene transfer between the organisms.
Mule is an offspring of interspecific hybridisation. Male and female animals of two different affiliated species are mated in this process. In the same conditions, the offspring will incorporate the beneficial characteristics of both the parents and may have significant economic benefit. A mule is a male donkey's offspring and a female horse.
Therefore the correct option is (B) Interspecific hybridisation.

Additional Information: Mule is tougher than a similar-sized horse and inherits the donkey sire's stamina and temperament, appearing to consume less food than a similar-sized horse. Mules appear to be more autonomous than other domesticated equines, rather than their kin, the donkey species.
For a mule, the median weight range is between around 370 and 460 kg. While a few Mules can bear up to 160 kg of live weight, the mule 's dominance becomes evident in its additional stamina.

Note: One of the biggest issues of selective breeding for individuals is that it can lead to the lack of diversity. This leaves no room for further future evolutionary expansion. Others oppose selective breeding as genetic mutation is not taken into consideration. Instead of removing evil, it can only maximise good traits. In fact, a depression in gene diversity may also lead to genetic mutation.
