Transplant experiments are often used to test if there is a genetic component to differences in populations.
Advances in molecular biology have provided researchers with the ability to study genetic variation more directly.
However, transplant experiments still have the advantages of being simple and requiring little technology.
On the other hand, they may require considerable time and labour, and the number of test organisms is often relatively limited.
