TRAITS, SURVIVAL, AND REPRODUCTION QUICK CHECK
#1: Which statement is correct about a bottleneck event?
-A bottleneck event increases the population of a species permanently.
-A bottleneck event decreases the gene pool of a population.
-A bottleneck event decreases the population of a species permanently.
-A bottleneck event increases the gene pool of a population.
#2: Why are the gene pools of small populations reduced compared to those of larger populations?
-lack of advantageous traits
-inbreeding
-bottleneck events
-lack of suitable mates
#3: A bottleneck event reduces the population of bears in one area by 80%. Which statement is correct about the bears’ gene pool?
-It has temporarily increased, so disadvantageous traits are less likely to be passed on.
-It has temporarily increased, so disadvantageous traits are more likely to be passed on.
-It has temporarily decreased, so disadvantageous traits are less likely to be passed on.
-It has temporarily decreased, so disadvantageous traits are more likely to be passed on.
#4: Which information helps scientists determine the survival probability of a population?
