Breeding two of the same species to get the best traits of each organism. A selectively bred cow can be useful for more milk production, more meat/leather, or breed more calves. Some other selectively bred animals are: horses,(for racing) chickens,(for food) and sheep,(for more wool). Selective Breeding

This cow has been selectively bred to put on more meat. Some advantages to this is that we can get more meat out of one cow and that there’s a less chance of them escaping. Disadvantages are that they can die young and the meat can go lame quickly. Selectively Bred Cow

Breeding animals that are or closely related to each other for many generations. Inbreeding is mostly done with dogs or cats to keep them a pedigree. Examples: People can sell certain breeds such as the golden retriever for high prices. Others can show them off at dog exhibitions or simply keep them a purebred. Inbreeding

This purebred dog produced pedigree pups which can give advantages and disadvantages. Advantages: They don’t lose as much vigor as a mixed breed. They also are good for exhibitions. Disadvantages: They’re fertility decreases and they have a higher risk of catching a disease. Inbreeding

Breeding 2 different organism to produce a hybrid organism with both parents’ traits. These are done for experimental purposes to help with future causes or problems for us and other organisms. Some examples are: producing a hybrid crop(such as corn) to withstand days without water, making an animal less susceptible to disease, or making a better organism out of the parents. Hybridization

A lion and a tigress mated to produce a liger. Other animals can be hybridized to produce a hybrid animal too. Advantages: Animal can catch less diseases with more genes. Can survive more than other animals. Disadvantages: Most hybrids cannot breed more of its type. Sometimes they can inherit bad genes from both parents Hybridization
