Antibody variation is also important for the bodies’ immune system. It allows antibodies to be produced that are specific for the different types of antigens found on pathogens that enter the body. During the primary immune response, B-lymphocytes take up the pathogens’ antigens and with the help of T helper cells produce specific antibodies. . These antibodies have a specific ...

Another example of variation is horses. Horses all belong to the same species as they can mate and produce offspring which are fertile. This means their offspring are able to reproduce.
In Science, inheritance is how parents pass on traits or characteristics to their children.
These characteristics (or traits) are passed down from one generation to the next in a family. We say they are inherited traits. Let's look at this a bit more. Inheritance in humans. We say that certain traits are passed down from generation to generation over many years, from parent organisms to their offspring.
The classification system is: Kingdoms, then phyla, then classes, then orders, then families, then genera and the smallest group is species . A species is a group of organisms that can interbreed with each other to produce fertile offspring.
Dogs are mammals as they are endothermic (warm-blooded), they have fur, they have mammary glands, they give birth to live young. Look at the dogs in the above picture and write down some common characteristics of the animals.
All living organisms that reproduce sexually produce offspring that are different from the parent organisms. Remember that we learned about sexual reproduction in angiosperms and humans in the last chapter. This allows the new organisms to be different to other organisms within the same species.
