Embryo Transplant Cloning

Animal clones can be produced by splitting apart cells from a developing animal embryo before they become specialised.

Why must cells be separated before they specialization?

What is Embryo Transplant Cloning?

"Embryo transplant cloning is a technique used to produce multiple genetically identical offspring from a single embryo."

Question 1

How many times does the cell divide during meiosis?

Question 2

Why is understanding the human genome important for modern medicine?

Question 3

Which group belongs to the domain Archaea rather than true bacteria?

Question 4

If both parents are heterozygous (Bb) for a recessive trait (b), what is the probability their child will express the trait?

Early Stage Cloning

Cells of a high-quality embryo are separated before they become specialised.

Each cell grows into an identical embryo.

The identical embryos are transplanted into surrogate mothers.

Exam Tip

This technique allows many identical, high-quality animals (e.g., prize cows) to be born from a single pregnancy.

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
