Through the years, people began to breed their dogs and cats with the intention for the pets to be useful in a certain skill. However, that has shifted to focus on their looks rather than their skills thanks to kennel clubs imposing standards on each breed. This has led irresponsible breeding practices to occur which in turn caused breeds to evolve negatively as breeds began to suffer from preventable genetic disorders and negative physical changes. Genetically manipulating soon shifted from pets to humans with PGD/IVF and CRISPR-Cas9. At first, there was a focus to use these methods to help cure and prevent genetic disorders. That has since shifted to people wanting to create the perfect child. In this thesis I will argue that designer breeds help lead the way to designer babies, and that any genetic manipulation to embryos should only be done if a medical reason is present.
