The diagram illustrates the replication of sheep embryos.
The process begins with the extraction of two particular types of cells from two sheep, followed by a series of processing stages, and culminates in the end product of a cloned lamb.
First of all, two female sheep named A and B are chosen to conduct the process. The wanted outcome is to produce a cloned lamb of Sheep A. To this end, a body cell is taken from Sheep A while an egg cell is extracted from Sheep B. The next step sees DNA from the body cell being extracted and nucleus is removed from the egg shell.
The process proceeds with the fusion of the DNA and the nucleus-free egg shell obtained from the previous stage of treatment. The fused cell created in this step develops into an embryo, which is then implanted in the uterus of another sheep named Sheep C. The process finishes with Sheep C, the foster mother, giving birth to a lamb, which bears the hereditary features of Sheep A.
