feeding pattern
reproductive rate. The number of offspring an organism can produce and the frequency at which they can reproduce significantly affects population size. Other factors like mortality rate, availability of resources, and environmental conditions also play a role in population growth, but reproductive rate is often the primary driver.
Climate is the major factor that determines where major ecosystems are located on the globe. An ecosystem is a community of organisms that live in the same physical environment.
Space is a limiting factor for a population because when the population starts growing then there won't be enough space for all the organisms so then some of the organisms have to leave that area and find a new habitat.
temperature
VO2max. This is one important factor (regarding lung function) which determines the total capacity for physical activity, along with muscle conditioning, nutritional factors and others.
population
Both abiotic and biotic factors determine both where an organism can live and how much a population can grow. A limiting factor is a factor that restricts the size of a population from reaching its full potential.

Which factor might determine whether the frequency of the new allele will increase in a population where a mutation occurs?
One factor that determines the number of representatives for a given Congressional District is the distribution of the population with a state. The more populated a state is, the more members that state can have in Congress.
Gene frequency
Variations within a population
