Question

Corrects for unequal evolutionary rates between sequences by using a conversion step. This conversion requires the calculations of “r-values” and “transformed r-values” using the following formula ______

(a) dAB’ = dAB − 1/4 × (rA + rB)

(b) dAB’ = dAB − 1/2 × (rA + rB)

(c) dAB’ = dAB − 1/3 × (rA + rB)

(d) dAB’ = (dAB/3) − 1/2 × (rA + rB)

The question was asked in an interview for internship.

Answer 1

The correct answer is:

(b) dAB' = dAB − 1/2 × (rA + rB)

This formula is used to correct for unequal evolutionary rates between sequences in the context of phylogenetic analysis. The "r-values" represent the evolutionary rates for sequences A and B, and the transformed distance (dAB') adjusts for these unequal rates to provide a more accurate measure of evolutionary divergence.
