Interspecific hybridization often results in sterile offspring due to genetic incompatibility.
A mule is the result of Interspecific hybridization.
(A) Out-crossing - Incorrect: Refers to breeding within the same species but unrelated individuals.
(B) Cross-breeding - Incorrect: Typically denotes breeding different breeds of the same species.
(C) Interspecific hybridization - Correct: Mules result from crossing horse (Equus caballus) and donkey (Equus asinus).
(D) Out-breeding - Incorrect: General term for avoiding inbreeding, not specific to hybrid crosses.
The correct answer is (C) Interspecific hybridization, producing this sterile hybrid of different Equus species.
A mule is the hybrid offspring produced by the mating of a male donkey and a female horse. This type of hybridization is known as interspecific hybridization, where two different species (donkey and horse) mate to produce an offspring.
