Genetically engineered babies by Praveen Kumar Shautha(EE)

A designer baby is a baby genetically engineered in vitro for specially selected traits, which can vary from lowered disease-risk to gender selection. Before the advent of genetic engineering and in vitro fertilization (IVF), designer babies were primarily a science fiction concept.

In future we can make a copy of our own genetic properties and can be directly implemented on a fetus,DNA chain through cloning!

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?
Gender
Appearance
Intelligence
Disease
Personality

Trait selection
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 baby
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

DNA Editing 
Genome editing, or genome editing with engineered nucleases (GEEN) is a type of genetic engineering in which DNA is inserted, deleted or replaced in the genome of a living organism using engineered nucleases, or "molecular scissors." 


The Future Of DNA editing 
Pronounced "crisper", it is a biological system for altering DNA. Known as gene editing, this technology has the potential to change the lives of everyone and everything on the planet.
A bold statement but that is the considered view of many of the world's leading geneticists and biochemists I've spoken to in recent months when working on my latest Panorama - Medicine's Big Breakthrough: Editing Your Genes.
CRISPR was co-discovered in 2012 by molecular biologist Professor Jennifer Doudna whose team at Berkeley, University of California was studying how bacteria defend themselves against viral infection.
 

Pros and Cons of Designer Babies 

Pros
Reduces risk of genetic diseases
Reduces risk of inherited medical conditions
Keep pace with others doing it
Better chance the child will succeed in life
Better understanding of genetics
Increased life span
Can give a child genes that the parents do not carry
Prevent next generation of family from getting characteristics/diseases

Cons
Termination of embryos
Could create a gap in society
Possibility of damage to the gene pool
Baby has no choice in the matter
Genes often have more than one use
Geneticists are not perfect
Loss of Individuality
Other children in family could be affected by parent's decision
Only the rich can afford it
