Which of the following would likely be shown on a topographic map? question 2 options: a)the estimated population of people in each area b)the height of the mountains in the area c) the speed limits on any of the roads or streets in the towns.
d)all of the above

answer: that would be cheating

explanation:

the right option is; decreased genetic variation  

decreased genetic variation describes the effect of this environmental change.

genetic variation is the naturally occurring genetic diversities or differences between organisms of the same species in a population. genetic variation allows the survival and adaptability of a species when they encounter changing environmental conditions. when an endangered species reduces, it loses genetic variation which may not be restored even if the species rebound and will only be recovered through the gradual collection of mutations over many years.
