a. It causes some genes to be removed from a population because there is a sharp decline in the population due to a natural disaster.
The bottleneck effect occurs when a population undergoes a drastic reduction in size, leading to a loss of genetic diversity. This can result in the removal of certain genes from the population as individuals with those genes are eliminated due to the bottleneck event. Over time, this can lead to genetic changes in the population as certain genes become less prevalent or disappear altogether.
How does the bottleneck effect lead to genetic changes in a population of organisms?
a
It causes some genes to be removed from a population because there is a sharp decline in the population due to a natural disaster.
b
It causes some genes to be added to a population because there is a sharp decline in the population due to a natural disaster.
c
It causes some genes to be removed from a population because there is a sharp increase in the population due to a natural disaster.
d
It causes some genes to be added to a population because there is a small decline in the population due to a natural disaster.
