Answer :
Final answer:
The density-dependent effect on population facilitates the spread of Aleutian disease by allowing the pathogen to transfer more efficiently in larger, denser populations.
Explanation:
The effect that is beneficial for the spread of Aleutian disease in the population is the density-dependent effect.
Density-dependent effects occur when the spread and severity of a disease are influenced by the size and density of the population.
In the case of Aleutian disease, which affects minks, larger and denser mink populations provide more opportunities for the disease to spread between individuals.
This can result in higher rates of transmission and a greater overall prevalence of the disease within the population.
