Farmers use selective breeding to produce dairy goats that give high milk yields.
Describe how selective breeding can be used to produce a herd of goats with high milk yields.
The diagram below shows an alternative way to obtain goats that produce high milk yields, called embryo cloning.
In this process, individual cells from an embryo known to have the genetic potential for high milk yields are separated before they become specialised. Each separated cell is then allowed to develop into a new embryo. These new embryos are then transferred to surrogate mothers.
Name the organ in the body of the surrogate mothers where the new embryos develop.
Suggest three advantages of producing goats with desirable characteristics using embryo cloning rather than using selective breeding.
Explain what is meant by the term clone.
Name the type of cell division that produces a multicellular embryo from a single cell.
