The concept of ‘designer babies’ has been a topic of debate for several years. Designer babies are babies whose genetic makeup has been artificially selected or modified using genetic engineering techniques. While the idea of having a child with desired traits may seem appealing, it also raises ethical concerns. But how did they develop designer babies? Let’s dive in and find out.

History of Designer Babies
The concept of designer babies can be traced back to the early 1900s. In 1907, the Eugenics Records Office was established in the United States. The office was responsible for collecting data on the genetic background of individuals to identify those with desirable traits. This information was then used to promote selective breeding to improve the genetic quality of the population.
Fast forward a few decades, and the discovery of DNA in the 1950s paved the way for genetic engineering. In 1978, the first baby was born through in vitro fertilization (IVF). This breakthrough opened up the possibility of manipulating genes in embryos to create desired traits in offspring.
Techniques Used to Develop Designer Babies
There are several techniques used to develop designer babies:
- Crispr-Cas9: This technique allows scientists to edit specific genes in an embryo. The technique involves introducing a protein called Cas9, which acts like a pair of molecular scissors, and a guide RNA molecule, which directs the Cas9 to the targeted gene. Once the Cas9 is at the gene, it cuts it, allowing scientists to either remove or replace it.
- Preimplantation Genetic Diagnosis (PGD): This technique involves screening embryos for genetic defects before implantation. The embryos are created through IVF, and a single cell is removed from each embryo for testing. The embryos that pass the screening are then implanted into the uterus.
- Artificial Insemination: This technique involves injecting sperm directly into the uterus, bypassing the natural process of fertilization. This allows for the selection of desired traits in offspring.

The development of designer babies raises several ethical concerns. One of the main concerns is the potential for discrimination against individuals who do not have the desired traits. There is also the possibility of unintended consequences, such as the creation of new genetic disorders.
There is also the question of who gets to decide what traits are desirable. This could lead to a situation where only the wealthy can afford to have designer babies, creating a further divide between the rich and poor.
The Future of Designer Babies
While the development of designer babies is still in its early stages, it is clear that it has the potential to revolutionize the way we think about reproduction. The ability to select or modify genes in embryos could lead to the eradication of genetic disorders and the creation of healthier offspring.
However, it is important to proceed with caution. The ethical concerns surrounding designer babies cannot be ignored, and careful consideration must be given to the potential consequences of this technology.
Conclusion
The development of designer babies has come a long way since the early 1900s. While the technology is still in its infancy, it has the potential to revolutionize the way we think about reproduction. However, the ethical concerns surrounding designer babies cannot be ignored. It is up to society to determine how this technology should be used to ensure that it benefits everyone.
Frequently Asked Questions
Q: Is it legal to develop designer babies?
A: The legality of developing designer babies varies by country. In the United States, there are no federal laws prohibiting the development of designer babies, but some states have enacted their own regulations.
Q: Can designer babies be created for cosmetic purposes?
A: While it is technically possible to create designer babies for cosmetic purposes, most countries have regulations in place that prohibit this practice.
Q: Is it possible to select multiple traits in a designer baby?
A: Yes, it is possible to select multiple traits in a designer baby using the Crispr-Cas9 technique. However, this increases the risk of unintended consequences and the creation of new genetic disorders.
Q: How much does it cost to develop a designer baby?
A: The cost of developing a designer baby varies depending on the technique used and the country in which it is developed. However, it is generally a very expensive process and is not accessible to everyone.
Q: What are the potential benefits of developing designer babies?
A: The potential benefits of developing designer babies include the eradication of genetic disorders, the creation of healthier offspring, and the ability to select desired traits in offspring.
