For each non-human species, what per cent of its amino acids are identical to the human sequence of β-globin?

The term non-human species is used for the organisms that are known to display few but not all characteristics of humans, so in some way, they are similar to humans but cannot be considered humans.

The non-human species are the ones that have specific characteristics just like humans, for example like monkeys, chimps, gibbons, and many more.

These non-human species may have the same ancestors, which may have diverged for some reason. In the given question, non-human species are shown as monkeys and gibbons.

In the given data, from analyzing the beta-globin sequences, it is clear that humans and monkeys have differences at eight places, so their percentage similarity will be less than the gibbons.

The total number of amino acids is one hundred forty-six, and out of which, one hundred thirty-eight will form similar amino acids, so the percentage obtained in such case will be percent.

After analyzing the sequence data provided in the question, one can say that the beta-globin sequences, in the case of humans and Gibbons, have differences in only two places. So, one can say that the percentage similarity of the genome of gibbons and humans is more than that of humans and monkeys.

In total, one hundred forty-six amino acids were analyzed, out of which similarity is observed at one hundred forty-four places, so one can easily calculate the percentage in such a case, which is per cent.
