Yes. Offspring of several different primate combinations have been created. Often, they do not exist for more than one generation though because they sometimes have confused sexual preferences, are infertile, or are excluded from social groups due to the differences in physical appearance. Some on the other hand, survive just fine. Primate hybrids are not extremely uncommon.
No, dogs and ducks cannot interbreed because they are too genetically different. They are from different animal families (Canidae and Anatidae) and have incompatible reproductive systems.
Because, genetically, they're not different species, but merely different breeds within that species. Genetically speaking, these two are related because they come from the same ancestor: the now-extinct European Aurochs. Because of that, they can and are able interbreed to produce viable and fertile offspring which can carry these genes for generations.
hybrids are produced when two different species interbreed
This is a tough question in the field of taxonomy. A species is classified as a group of organisms that can interbreed. However, this is more more complicated. Suppose Organism A can successfully interbreed with Organism B, Organism B with Organism C, and Organism C with Organism D; however, Organisms A and D are too genetically different to interbreed. Is this one species or multiple species? Does it really matter? Why do I keep asking questions about schizophrenia and why do I?
No. They have different numbers of chromosomes.
Neanderthals and humans are genetically similar. Less than one percent difference in their DNA.
These organisms are considered to be members of the same species. They are reproductively compatible with each other but genetically isolated from all other organisms.
No, they are different species and can not interbreed.
no they are different species, they cannot interbreed
Not necessarily. Organisms that look different can belong to the same species if they can interbreed and produce fertile offspring. Organisms that look similar can also belong to different species if they are reproductively isolated and cannot interbreed successfully.
No, they do not. They are 2 different species, and cannot interbreed.
Means a species always has that potential to breed, one with another. Still, different populations of that species may be too geographically divided to actually interbreed.
