Question

to ensure that we are being accurate and random during population sampling, which individuals do we want to capture each time we conduct a recapture? only the marked individuals only the females without marks both marked and unmarked, random individuals specific individuals with no marks

Explanation:

In population sampling (like mark - recapture methods), to ensure accuracy and randomness, we need to capture both marked (from the initial capture) and unmarked individuals randomly. Capturing only marked, only unmarked (with gender bias or specific unmarked), or specific unmarked individuals would introduce bias and not give an accurate estimate of the population. So the correct option is the one that includes both marked and unmarked individuals selected randomly.

Answer:

C. both marked and unmarked, random individuals
