Organisms of the same species will share common traits.
Same genus or closely related species.
A group of the same species that live in the same area is called a population. In ecology, a population refers to all the individuals of a species that live together in a specific geographic area at a given time. Populations interact with each other and their environment, playing a crucial role in the dynamics of ecosystems. Understanding population dynamics is essential for studying species distribution, abundance, and conservation.
the definiton of a species is two organisms that have changed from each other so much that they cannot have any viable offspring. So basically they cannot mate.So a taxonomist would be able to tell if the two plants were of the same species or not by polinating one with the other, like how bees pollinate plants, and see if they produced seeds and then if those seeds were able to produce mature plants.
To tell if organisms are similar you need to use the genus, species name always changes. For example: wolves and domestic dogs. A wolf's scientific name is canis lupus. A dog's scientific name is canis familiaris. All animals in the dog family start with canis, then from there there species name, and then from there, there is the sub-species name.

You look for features that are the same
You can tell how closely related organisms are by determining the lowest classification that they share. For example, organisms that share the same genus will be more closely related than organisms that share the same family.
Not if they are all members of the same team!
dna if coloring the same for the species
Simply by looking at it and comparing it with others of the same species.
The genus of an organism tells us its broader classification within the biological hierarchy. It indicates that the organism shares certain traits with other species in the same genus and is more closely related to them than to species in other genera. Additionally, organisms within the same genus are likely to have a more recent common ancestor compared to those in different genera.
Two species are typically placed in the same genus based on shared physical characteristics, genetic similarities, and common evolutionary ancestry. Taxonomists consider a combination of these factors when determining the classification of species into different genera.
