Final answer:
In a population of fig wasps, where many matings are between full siblings, you would expect to observe individuals with the greatest inbreeding depression.
Step-by-step explanation:
The population in which you would expect to observe individuals with the greatest inbreeding depression would be a. A population of fig wasps, where many matings are between full siblings. Inbreeding depression occurs when related individuals mate and their offspring experience reductions in reproduction and survival. In the case of fig wasps, where many matings are between full siblings, the combination of related genomes during fertilization can result in increased abnormalities and disease.
