Question

Which of the following is incorrect statement?

(a) In this method one half of the sites in a dataset are randomly deleted

(b) It creates datasets half as long as the original

(c) Each new dataset is subjected to phylogenetic tree construction using the different methods as the original

(d) One criticism of this approach is that the size of datasets has been changed into one half and that the datasets are no longer considered replicates

I have been asked this question in final exam.

Question is taken from Phylogenetic Tree Evaluation in chapter Phylogenetic Tree Construction Methods and Programs of Bioinformatics

Answer 1

Correct option is (c) Each new dataset is subjected to phylogenetic tree construction using the different methods as the original

Easy explanation: Each new dataset is subjected to phylogenetic tree construction using the same method as the original. The advantage of jackknifing is that sites are not duplicated relative to the original dataset and that computing time is much shortened because of shorter sequences.
