Question

question 3 1 pts some hybrid organisms survive but do not produce fertile offspring. this is a postfertilization isolating mechanism called
○ hybrid inviability
○ hybrid infertility
○ temporal isolation
○ gamete incompatibility

Explanation:

• Hybrid inviability refers to hybrids that do not survive to reproductive age, so it's not this.
• Hybrid infertility (also called hybrid sterility) is a post - fertilization isolating mechanism where hybrids survive but cannot produce fertile offspring, which matches the description.
• Temporal isolation is a pre - fertilization mechanism (organisms breed at different times), so it's incorrect.
• Gamete incompatibility is a pre - fertilization mechanism (gametes can't fuse), so it's incorrect.

Answer:

B. Hybrid infertility
