Which symptom would an individual with a narrow foramen most likely experience?

Which foramen? The human body has several. A foramen is an opening. If something is flowing through the foramen, the narrowing of a foramen will either restrict the rate of flow of whatever substance was normally travelling through the opening, or the pressure needed to maintain the rate of flow will increase.

from the original order (top to bottom) the new order will go

1 (founder)

4 (hawk)

2 (mutate)

3 (next generation)

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
