<span>Simple.
All of the millions of different life forms (the diversity of life) have come about by natural selection, whereby random mutations in the genes have either succeeded or failed.
But all life can be traced back to a common single-celled origin. Thus we have the unity of life where we (possibly) share more than 50 % of our DNA with a crocodile.eg:analogous organs, homologous organs.</span>
Anemia is a blood disorder caused by a lack of iron and red blood cells.

Metaphase I follows prophase I and precedes anaphase I.
Explanation:
Once you have obtained your salmon sample from a local store, you need to isolate the DNA from it and make many copies of the COI gene using the polymerase chain reaction (PCR).
