Which of the following results from a mark-recapture study done on mice would reflect a larger population size? When taking the second sample, 200 individuals are caught and 80 are marked from the first sample. Both of these scenarios would result in the same population estimate. When taking the second sample, 200 individuals are caught and 20 are marked from the first sample.

Option (3).

Explanation:

Mark recapture method is used for the estimation of population size of an area. The individuals are identified by some mark on them. The formula of mark recapture method is

N = M * C / R

Here, N is the number of the individuals, M is the individuals are marked and captured, C is the individual captured again with mark or non mark and R is recaptured marked individual.

The individual with 200 population, 20 are marked for the first time represent the large population size.

Thus, the correct answer is option (3).
