A novel and efficient method for production of a transgenic animal is developed. This invention provides a method for production of a novel transgenic animal comprising the steps of introducing a foreign gene into testis of an animal, selecting transfected spermatocytes, spermatids or spermatozoa in which the foreign gene was introduced using a fluorescence marker gene as an indicator and fertilizing an unfertilized oocyte or ovum with the transfected spermatocyte, spermatid or spermatozoa. |
