Are there any contradictions of phylogeny based on predictions with the HBB gene

Question

Are there any contradictions of phylogeny based on predictions with the HBB gene vs. the beta actin gene (you may construct a separate phylogenetic tree or you can simply draw your conclusion based on the % identities compared to human)?   Discuss when you think when is using the HBB gene more appropriate and when is using the beta actin gene is more appropriate in terms of phylogeny prediction.

Pan (taxid: 9596): Identity % - 99%       Cover Query % - 100%

Dogs (taxid: 9615): Identity % - 94%     Cover Query % - 100%

Cats (taxid:9685): Identity % - 93%       Cover Query % - 100%

Mouse (taxid:10088): Identity % - 92%    Cover Query % - 100%

Chicken (taxid:9031): Identity % - 90%     Cover Query % - 99%

Salamanders (taxid:8293): Identity % - 86%    Cover Query % - 99%

Snakes (taxid:8570): Identity % - 88%      Cover Query % - 99%

Fish (taxid:7898): Identity % - 89%    Cover Query % - 99%

Drosophila (fruit fly – taxid:7215): Identity % - 88%    Cover Query % - 98%

budding yeast (taxid 4892): Identity % - 79%      Cover Query % - 99%

grass family (taxid:4479): Identity % - 86%     Cover Query % - 98%

paramecium (taxid: 5884): Identity % - 66%    Cover Query % - 97%

Explanation / Answer

The evolution and phylogeny of species is studied by observing the recombinational mode of origin and the nature of functional divergence between the parental genes. Mammals show more similarity in the HBB genes. The ?-globin gene family of placental mammals provides an excellent system for investigating the evolutionary fates of chimeric fusion genes which is influenced by their recombinational mode of origin.

Actin is one of the most highly conserved proteins encoded by a multigene family. It is found in all eukaryotic cells.

While studying the phylogeny of mammals with the humans the HBB gene is more appropriate. For observing the phylogeny of species other than the mammals with humans, beta actin gene is more appropriate in terms of phylogeny prediction.
