Question

A scientist is studying coat color in three different populations of field mice. Brown coat color is dominant to grey coat color.
Below is a data table showing the number of brown and grey mice in each of the three populations
Coat Color in Field Mice

	Brown	Grey
Population X	18	2
Population Y	180	20
Population Z	54	6

Which population is most likely to be subject to the bottleneck effect?

• A. Population X
• B. Population Y
• C. Population Z
• D. It is impossible to tell from the information given.

Answer 1

Answer: (D)

It is impossible to tell from the information given.

It is not possible to tell from the information as the natural calamity has reduced the frequency of the alleles in all the three population in the same ratio,that is 9:1

So, the correct answer is 'It is impossible to tell from the information given'
