Family and kingdom
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.
Same genus or closely related species.
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.
No, organisms that are closer together on a phylogenetic tree are more closely related because they share a more recent common ancestor. The further apart two organisms are on the tree, the more distant their relationship.

Clasifiaction
True. The more distantly related two organisms are in evolutionary terms, the fewer homologous structures they are likely to share. Homologous structures are features that have a common evolutionary origin, so closely related organisms are expected to have more similarities in their structures compared to more distantly related organisms.
true
If two organisms share multiple classification levels, it means they have similarities in their evolutionary history and genetic makeup. This suggests that they are closely related and likely share a common ancestor. Organisms that share more classification levels are more closely related than those that share fewer levels.
When using genus and species in taxonomy , the genus will be the same for two very closely related organisms. The species will separate them.

Scientists mainly compare similarities and differences in what the organisms look like. With the less obvious relations, they analyze their DNA. The goal is to find a common ancestor between the two organisms. The more recently that ancestor existed, the more closely related the organisms are.
