No, a gorilla and a human have never successfully mated. Such an event is genetically impossible due to fundamental differences in their biological makeup.
Genetic Incompatibility
While humans and gorillas share a significant portion of their DNA, the successful mating and production of viable offspring between the two species is prevented by a critical genetic barrier: the number of chromosomes.
Chromosome Differences
Humans and great apes (including gorillas, chimpanzees, and orangutans) possess different numbers of chromosomes. Chromosomes are the structures within cells that contain a person's genes. For successful reproduction, two individuals typically need to have the same number of chromosomes that can pair up correctly during cell division.
The distinct chromosome counts are as follows:
| Species | Chromosome Pairs | Total Chromosomes |
|---|---|---|
| Human | 23 | 46 |
| Gorilla | 24 | 48 |
This difference in chromosome number makes it genetically impossible for a human and a gorilla to produce a hybrid offspring. Even if mating were to occur, fertilization would likely not lead to a viable embryo, as the differing chromosome sets cannot properly combine to form a new organism. The genetic incompatibility ensures that these two species remain distinct and cannot interbreed.

Why Chromosome Numbers Matter
The precise pairing of chromosomes during the formation of reproductive cells (sperm and egg) and subsequent fertilization is crucial for the healthy development of an embryo. When the chromosome numbers differ, as they do between humans and gorillas, the genetic material cannot align and segregate properly. This leads to severe developmental issues, making hybrid offspring non-viable or impossible to conceive in the first place. This is a common biological barrier that maintains the integrity of distinct species across the animal kingdom.
