Questions from this subtopic

Each one with the model answer underneath.

1
How do natural clones arise in animals?
Model answer
Through embryo splitting, where a single early embryo divides to form two or more genetically identical individuals.
2
What are identical twins?
Model answer
Natural clones formed when an early embryo splits into two separate cell masses that each develop into a complete, genetically identical organism.
3
What is the first step in artificial embryo twinning?
Model answer
Collection of an early embryo from a donor animal.
4
How is the embryo divided in artificial embryo twinning?
Model answer
The early embryo is mechanically separated into two or more cell masses.
5
What happens to the separated cell masses in artificial embryo twinning?
Model answer
Each cell mass is implanted into a separate surrogate mother.
6
What is the outcome of artificial embryo twinning?
Model answer
Each implanted cell mass develops into a genetically identical individual.
