Why can the reduction in melting temperature for hybrid DNA between two mammalian species be used to predict how long it has been since those species diverged from a common ancestor? A., Mutations in DNA accumulate at a fairly constant rate. B., Closer relatives have fewer DNA base pair mismatches. C., Closer relatives are less likely to be reproductively isolated.
