Hybrid in biology means when two different species come together to create a new one that has a mix of characteristics from both parents. It's like when your mom and dad have a baby, the baby has some traits from both of them, like eye color or height. But with hybrids, the parents are from different species, like a horse and a donkey creating a mule.
When two different species mate, their genes mix and create a new kind of creatures called hybrid. The hybrid can have different traits from each parent, or it can be a mix of both parents' traits. For example, a tiger and a lion create a liger that has stripes like a tiger and a mane like a lion.
Hybrids are different from purebred animals because purebred animals are the result of mating two animals of the same species. However, hybrids sometimes cannot mate and produce offspring because they are sterile. That means they cannot pass on their genes to their own children.
In conclusion, hybrid is when two different species mate and create a new kind of creature that has traits from both parents, but sometimes, they cannot mate and produce offspring because they are sterile.
