Question

Sequence similarity can be quantified using ________ homology is a ______ statement.

(a) percentages, quantitative

(b) percentages, qualitative

(c) ratios, qualitative

(d) ratios, quantitative

I have been asked this question in an online quiz.

Question is from Sequence Homology Versus Sequence Similarity and Identity in section Pairwise Sequence Alignment of Bioinformatics

Answer 1

The correct answer is (b) percentages, qualitative

To elaborate: Similarity is a direct result of observation from the sequence Alignment. For example, one may say that two sequences share 40% similarity. It is incorrect to say that the two sequences share 40% homology. They are either homologous or nonhomologous.
