C. 100 member founding population
The bottleneck event that the cheetah went through in the last ice age ultimately resulted in a stronger, more robust species.
The Amish are an example of a population where the founder effect has resulted in generally rare genetic traits being more commonly expressed.
The disproportionately high appearance of polydactylism among the Amish suggest that
C. It was overrepresented in the gene pool of the original Amish settlers
Genetic drift is best described as the redistribution of the frequency of gene occurrence in a(n)
The Toba supervolcanic event caused a bottleneck in the human population by
C. Including an ice age
A species that has experienced a severe bottleneck event would be expected to
C. Be more susceptible to disease and famine
In nature, this method is the only way diversity is truly created. Changes in the genetic material of an organism are passed on to offspring and, although the process is slow, it could eventually result in the creation of a new species. These statements describe the effects of _______ on biodiversity.
The unusual maintenance of genetic diversity among the Mouflon in the Indian Ocean after a severe reduction in their population is mostly due to environmental pressures on the island where they lived.
Which of the following is not a potential result of the bottleneck event?
A. An increase in potential mates
Bottleneck events are always caused by the deaths of most of a species' population.
The bottleneck event that decimated the bison was caused by
