Today students learned about selective breeding. Selective breeding is when two organisms with desired traits are selected to serve as the parents to the next generation. We are studying two types of selective breeding, inbreeding and hybridization. Inbreeding involves crossing two individuals who have identical or similar sets of alleles, which will result in the offspring's traits being very similar to their parents. An easy example or model for students to understand is dog breeding. For example, two pug parents make pug puppies. Hybridization occurs when breeders cross two genetically different individuals, which results in the offspring inheriting the best traits of both parents. Examples of hybrid dogs include puggles, cockapoos, labradoodles, goldendoodles, pomapoos, and so forth.
