Question

Molecular phylogeny is based on the idea that-

• A. Organisms which are most distantly related will accumulate greater number of differences in their DNA
• B. Organisms which are most distantly related will accumulate lesser number of differences in their DNA
• C. Estimating the ratios of different isotopes of the same element in the fossil material, helps in detecting age of fossil
• D. Shaping of diversity by slow and continuous process

Answer 1

The correct option is A Organisms which are most distantly related will accumulate greater number of differences in their DNA

Molecular phylogeny is the process by which evolutionary relationships can be checked or studied at molecular level by evaluating DNA. Closely related organisms will have similar DNA sequences and the organisms which are distantly related will accumulate a larger number of differences.
