Hen give birth to duck egg
With the development of science and technology, the chicken giving birth to duckis not a fantasy. The team which developed the world’s first cloned sheep “Dolly,” today announced a new breakthrough: With genetic modification techniques, make a hen to duck and successfully hatched.
How to manufacture different kinds of descendants? Scientists need to extract sperm and egg cells from bird embryos, and then implanted in the reproductive organs of the embryo. When the genetically modified chickens grow up and begin to manufacture the sperm of the species of birds, gave birth to the descendants.
