The Ethics of Animal Cloning at the Embryo Stage
TLDR; Animals can be cloned at the embryo stage, creating genetically identical individuals with the potential to develop into individuals. However, it raises ethical and moral concerns.
⚛️ Embryo Development
Embryo development starts with the fusion of a sperm cell and an egg cell, resulting in a single cell with half the genetic information from each parent.
Through a series of divisions, the single cell develops into multiple identical cells, known as embryonic cloning.
At this stage, all cells are pluripotent, meaning they have the potential to develop into any type of cell in the body.
🧬 Genetic Identity
When a ball of cells is split, the resulting cells are genetically identical to each other, with the same DNA sequence, genome, and genes.
Theoretically, these genes will be expressed the same way because the DNA sequence is 100% identical, although there might be a few mutations due to errors in DNA replication.
All cells at this early stage are pluripotent, meaning each cell has the potential to develop into an individual.
👥 Natural Cloning
Coral embryos naturally split and turn into multiple copies and clones of each other, illustrating the natural occurrence of cloning at the embryo stage in animals.
This process may have been the technique used in the Star Wars film, The Clone Wars, to create identical animal twins.
👫 Identical Twins
The splitting of the fertilized egg can result in identical animal twins, where both individuals are genetically identical.
This phenomenon is similar to the development of identical human twins at the early stage of embryo development.
⚠️ Ethical Concerns
Cloning at this early stage raises ethical concerns due to the uncertainty about the characteristics and traits of the cloned individual.
There are moral and ethical discussions surrounding the desirability and potential traits of the cloned individual, as well as the implications for society.
Given the ethical and moral implications, cloning at this stage is not a popular method, and it's advised against attempting it at home.
