Humans and chimpanzees are closely related organisms, sharing a common ancestor. Additionally, dogs and wolves are closely related, with domestic dogs descending from wolves through selective breeding.
Organisms that are closely related to rabbits include; horses and turtles
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.
Closely related: obelia jellyfish Not closely related (but still related): coral sea anemone

Organisms in the same genus are most closely related to one another according to Linnaeus's groupings.

Selective breeding is a method of breeding that allows only those individual organisms with desired characteristics to produce the next generation. Humans use selective breeding, which takes advantage of naturally occurring genetic variation, to pass desired traits on to the next generation of organisms.Hybridization is the crossing of dissimilar individuals to bring together the best of both organisms.Inbreeding is the continued breeding of individuals with similar characteristics to maintain desired traits within a line of organisms.
Same genus or closely related species.
Two types of selective breeding are inbreeding and outbreeding. Inbreeding involves mating closely related individuals, increasing the chance of inheriting both desirable and undesirable traits. Outbreeding, on the other hand, involves mating unrelated individuals, which can increase genetic diversity and reduce the prevalence of genetic disorders.
In breeding closely related animals increases the risk of genetic problems due to the lack of genetic diversity. This can lead to an increased likelihood of inheriting harmful genetic mutations and an increased prevalence of genetic disorders in the population. It is important to carefully consider genetic diversity and potential health issues when breeding closely related animals.
