Colorado has a vast population of lodgepole pines. a population of lodgepole pines have been killed in a section of the forest. what is a possible limiting factor of that population? a. devastation by the pine bark beetle b. colorado’s long history of acidic soils c. genetic variability d. shallow root system

Answer;

A. Devastation by the pine bark beetle

Explanation;

If the presence or absence of a factor limits the growth of the ecosystems elements, it is called a limiting factor.

There are several abiotic factors that limit ecosystem growth, including temperature, precipitation, sunlight, soil configuration, and soil nutrients.  Some limiting factors depend on the size of the population. Other limiting factors affect all populations in similar ways, regardless of the population size.

the father in the first generation probably had the recessive colorblind trait in his x chromosome. if he and his wife both had the colorblind trait, even if she had 1 recessive and 1 dominant, then that trait would be passed on to their kids.

(since you didn't attach the family tree this is just an assumption)
