Question

the offspring produced between the mating of a tiger and a lion, a liger, which is unable to reproduce, is an example of which form of reproductive isolation?
○ gametic isolation
○ temporal isolation
○ behavior isolation
○ hybrid inviability
○ hybrid infertility

Explanation:

The question describes a ligers (hybrid of tiger and lion) that cannot reproduce. Hybrid infertility refers to the inability of a hybrid offspring to produce viable gametes, leading to reproductive failure. This matches the scenario, while other options describe pre-zygotic barriers (gametic, temporal, behavior isolation) or hybrid inviability (failure to develop to maturity), which are not the case here.

Answer:

hybrid infertility
