They have been aligned. That is, regions of similarity have been arranged one above the other. Mutations have been indicated by underlining and bolding. Using what you know about the structure of the genetic code and the way in which mutations accumulate in DNA sequences, circle the most likely first full codon in the sequence fragments as you begin to read from the left. As indicated in the seqence, the mutations are in the third position.
Mutations accumulate in different types of sequences at different rates.
Below are three types of sequences. From the choices below, circle the correct order which lists them from that sequence which accumulates mutation most rapidly to that sequence which accumulates mutation the slowest. Mutations are removed from the population Pseudogenes no longer produce a protein mutations in pseudogenes do not affect fitness organisms with these mutations leave offspring so these mutations are seen in the population 7. The echidna is a marsupial with quills derived from hair and the porcupine is a mammal with quills derived from hair. The are homologous because both of the quills arise from hair.
