Question

Table : The extent of genetic divergence for seven genes between vertebrates and the reference taxon and invertebrates and the reference taxon. (Metaphytes are multicellular plants.) A) Compare the amount of divergence genes between vertebrates and the reference taxon and invertebrates and the reference taxon for each of the genes and for each of the reference taxa. Are there any genes for which the divergence to invertebrates was markedly (1.5 times or more) greater or markedly less than the divergence to vertebrates? B) Did NADH1 evolve faster in invertebrates or in vertebrates? Explain your reasoning. Reference taue Vertebrates ATPase 6 Metaphyte Eubacterium Eubacterium taphyte cast Eubacterium Hemoglobin Metaphyte 49 4-66 1.04 Protist 5.34 | LO154 Eubacterium NADH I Slime mold 94 0024 Eubacterium 28S rRNA Metaphyte Fungus

Explanation / Answer

A) For ATPase 6 and hemoglobin, the divergence in invertebrates is 1.5 times or more.

B) NADH has evolved faster in the vertebrates than the invertebrates, though the difference in time of evolution is not very vast. This can be seen from the difference in the mean value, which is lower in every case in the vertebrates and also the SEM value, which is almost 0.5 times of the invertebrates.
