Answer:
Polygenic traits
Explanation:
Polygenic traits are traits that are controlled by more than one gene and the physical expression of these genes is significantly influenced by environmental conditions .Characteristics that show continuous variations are controlled by many genes.The genes that control them may be located near each other or even on separate chromosomes. They are often represented as a range of continuous variation because they are not discrete.

Answer: (c) A local wolf population experiences a lethal epidemic of parvovirus.
Explanation:
A limiting factor is one which is capable of limiting the population of the species. It can be a living factor or a non-living factor.  
The density dependent limiting factor is a factor which affects the population of a species depending upon the size of the population. There are many density dependent limiting factors such as disease, migration, predation and food.  
C is the correct option, this is because of the fact that the epidemic outbreak can spread over to the large number of members of the population. If larger the population size more likely will be the chances of spreading.
