Question

Interspecific hybridisation is the mating of

• A.
  animals within same breed without having common ancestors
• B.
  two different related species
• C.
  superior males and females of different breeds
• D.
  more closely related individuals within same breed for 4–6 generations

Answer 1

The correct option is B

two different related species
Interspecific hybridization refers to cross between two individuals of two different species or different genera to bring their characters together in the hybrid progeny. Superior males and females of different breed or same breed belong to same species.

A cross between superior males and females of different breeds refers to cross breeding while that between animals within the same breed without having common ancestors is called as outcrossing.

Mating of more closely related individuals within the same breed for 4-6 generations is called inbreeding.

So the correct option is "two different related species"
