What are the advantages and disadvantages of the capture-mark-recapture method

Capture-mark-recapture method is a technique commonly used to measure the size of a population. When using this technique, a number of individuals in a certain natural population are marked, returned to that population, and some of them are eventually recaptured as a basis for estimating the size of the population at the period of marking and release.

Advantages of the capture-mark-recapture method include; it is relatively costly, reliable, and its accuracy does not depend on the evaluation of the amount of habitat.

Disadvantages of the capture-mark-recapture method include; its accuracy depend on capturing a large proportion of the population, and marking of animals can have a dramatic effect on the animals.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
