Question

The KH test sets out to test the null hypothesis that the two competing tree topologies are not significantly different.

(a) True

(b) False

I got this question in a national level competition.

This question is from Phylogenetic Tree Evaluation topic in division Phylogenetic Tree Construction Methods and Programs of Bioinformatics

Answer 1

The correct answer is:

(a) True

The KH (Kishino-Hasegawa) test is used in phylogenetic analysis to compare two competing tree topologies and test the null hypothesis that these two topologies are not significantly different. Essentially, it assesses whether one tree is significantly more likely than another based on the given data. If the null hypothesis is rejected, it suggests that one of the tree topologies is significantly better than the other.
