Read the passage below and answer the questions that follow.
Transgenic Rabbits The microinjection of human genetic material into fertilized animal eggs allows the production of transgenic livestock. Rabbit eggs are fertilized in vitro and a human gene is microinjected into the pronucleus. These eggs develop into early-stage embryos, which are then surgically transferred into the uterus of surrogate mothers.
A transgenic female rabbit named Evelyn was successfully created to express human erythropoietin in her milk. Erythropoietin is a hormone that stimulates the production of red blood cells. When she matured, Evelyn was bred with a normal, non-transgenic male rabbit. She gave birth to a litter of 15 offspring, of which 12 successfully inherited the transgene and the ability to produce erythropoietin in their milk.
Explain what is meant by the term gene.
In which part of the surrogate mother are the embryos implanted?
What percentage of the offspring from Evelyn's litter were confirmed to inherit the transgenic DNA?
