  1. Tinkering with Inheritance By Kevin Ocsena and Celine Matos

  2. Selective Breeding • 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).

  3. Selectively Bred Cow • 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.

  4. Inbreeding • 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.

  5. 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.

  6. Hybridization • 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.

  7. 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
