Question

12. Interspecific crosses mostly produce sterile hybrids. Such crosses are not favoured by nature
because their high frequency may
(a) produce variations in organisms
(b) affect continuity of species on earth
(c) decrease availability of food and other resources
(d) produce a new species​

Answer 1

Answer:

the option is 2

Explanation:

as these hybrids are sterile they cannot reproduce and thus their continuity on earth is affected

Answer 2

Interspecific crosses mostly produce sterile hybrids. Such crosses aren't favoured by nature because their high frequency may affect continuity of species on Earth.

Explanation:

Option 2 is the correct answer.

The interspecific cross is carried out between two different species that results in the production of sterile offsprings. It is preferred commercially to produce superior individuals. However, it is not favoured naturally because it may affect the continuity of the species on earth as they produce sterile hybrids. These hybrids are not able to reproduce further. So the high frequency of such hybrids may cause extinction of the original species.
