How do you make a designer baby?

Creating a designer baby typically involves advanced genetic engineering techniques, such as CRISPR-Cas9, to modify an embryo's DNA before implantation. This process can be used to eliminate genetic disorders or enhance specific traits, such as intelligence or physical appearance. However, ethical concerns surrounding the implications of such modifications, including potential long-term effects and societal inequalities, remain a significant topic of debate. As of now, the technology is still largely experimental and regulated in many countries.
