What Are Designer Babies?
The colloquial term "designer baby" refers to a baby whose genetic makeup has been artificially selected by genetic engineering combined with in vitro fertilization to ensure the presence or absence of particular genes or characteristics. - wikipedia
In simpler terms, using biotechnology to choose what type of baby you want. Latest research is making designer babies a reality now, using technology developed originally for use in animals.
What traits could be changed in a designer baby?
Embryo screening involves a process called pre-implantation genetic diagnosis (PGD). Embryos are created by in-vitro fertilization and grown to the eight-cell stage, at which point one or two cells are removed. Scientists then examine the DNA of these cells for defects, and only normal embryos are replaced in the womb.
Three-parent babies are human offspring with three genetic parents, created through a specialized form of In vitro fertilisation in which the future baby's mitochondrial DNA comes from a third party. The procedure is intended to prevent mitochondrial diseases including muscular dystrophy and some heart and liver conditions. It is the subject of considerable controversy in the field of bioethics. - wikipedia

Essays are used to assess your understanding of specific ideas and your ability to explain these in your own words.
Essays are usually written in a discursive style, bringing together ideas, evidence and arguments to address a specific problem or question.
They follow a particular structure: you will set out your argument in the introduction, build and present your argument in the main body, and should end with your overall key message or argument in the conclusion.
Essays take time to complete. You will need to set aside time for the following stages of writing:
- Thinking about the question.
- Gathering information and ideas.
- Organising your ideas.
- Getting something on paper.
- Writing a first draft.
- Reviewing in light of feedback or reflection.
- Producing a final draft.
