Hello Jiskha members. I am doing a science assignment currently and I need my answers checked as I am unsure of if I am correct.
Which statement is correct about a bottleneck event? (1 point)
A bottleneck event increases the gene pool of a population.
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.
Why are the gene pools of small populations reduced compared to those of larger populations? (1 point)
lack of advantageous traits
lack of suitable mates
inbreeding ****
bottleneck events
A bottleneck event reduces the population of bears in one area by 80%. Which statement is correct about the bears’ gene pool? (1 point)
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. ****
It has temporarily increased, so disadvantageous traits are less likely to be passed on.
Which information helps scientists determine the survival probability of a population? (1 point)
the existence of natural selection in the population
the number of offspring of an individual in the population
the feeding habits of an individual in the population
the level of genetic variation in the population ****
Please do not use letters in your answer. Sometimes the answers in the assignment are shuffled.
Example: Instead of doing C D A C, tell me the words.
Thank you so much!
