Free mixing of marked and unmarked individuals would not bias the estimate because it would not affect the proportion of marked individuals recaptured in subsequent samples, which is the key factor in the mark-recapture method. The other options could potentially bias the estimate by altering the proportion of marked individuals recaptured.
