Organisms in the same genus are most closely related to one another according to Linnaeus's groupings.
Clasifiaction
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
To determine which two organisms are most closely related, Serena should compare their genetic similarities, physical characteristics, and evolutionary histories. Organisms that share a recent common ancestor and exhibit similar DNA sequences or structural traits are typically considered more closely related. Analyzing phylogenetic trees can also provide insight into their evolutionary relationships. By focusing on these factors, Serena can make a well-informed conclusion about their relatedness.
Organisms that are in the same genus, which is the level just above species in the taxonomy chart, are most closely related. They share more recent common ancestors compared to organisms in the same family, order, or class.
Organisms in the same genus are most closely related to one another according to Linnaeus's groupings.
Clasifiaction
The taxon that includes organisms that are most closely related is a species. Organisms within the same species share a high degree of genetic similarity and can interbreed to produce fertile offspring.
Thesus monkey is the most closely related to Humans because it has the least number of differences in cytochrome c.
Canis familiaris (domestic dog) is most closely related to Canis lupus (wolf).
DNA sequence similarity is the most useful factor in determining whether two organisms are related. The more similar the DNA sequences of two organisms are, the more closely related they are likely to be evolutionarily.
Organisms that are most closely related share a more recent common ancestor than other organisms. This can be determined through genetic analysis, looking at similarities in DNA or protein sequences. Generally, organisms within the same species, followed by those within the same genus, are most closely related.

In the classification of organisms, family is a higher taxonomic rank than genus, and genus is a higher rank than species. Organisms that belong to the same genus are more closely related than those in the same family, and organisms in the same species are the most closely related.
Humans are most closely related to chimpanzees.
