Answer:
B. Is more closely related to frogs than to humans.
Explanation:
The amount of changes observed in a given gene from two different species is directly proportional to the divergence time. This means that if two species diverged recently, there will be few differences because there hasn't passed enough time for them to accumulate mutations. If two species diverged a long time ago, you will be able to observe many differences between the two homologous genes. The shorter the divergence time between two species, the closer they are related. Knowing this, you can conclude that the new organism will be more closely related to the species that it is more similar to, and in this case, that species is the frog, that only shows 5 differences in the hemoglobin when it's compared to the new species.

Answer:
Hemoglobin, or haemoglobin, abbreviated Hb or Hgb, is the iron-containing oxygen-transport metalloprotein in the red blood cells of almost all vertebrates as well as the tissues of some invertebrates. Hemoglobin in blood carries oxygen from the lungs or gills to the rest of the body.
Answer: incomplete dominance
-----
In incomplete dominance, a possible phenotype is neither the dominant or recessive trait, but a blend of both alleles. This is seen in snapdragons when a red and white flower breed, creating a pink flower.
