Genetic Analysis in Mammals: Past, Present, and Futureogy. Today, we have in our scientific repertoire the ability to examine gene action virtually by direct observation and to put to the test the scores of intriguing hypotheses that have emerged during the deductive period of genetics.

A Technique for Bisection of Embryos to Produce Identical Twins the embryo in a single step. These methods were attempted with various difficulties in our laboratory. Spatial visualization was difficult when attempting needle cutting against the holding pipette with a Leitz Diavert inverted microscope. The alternative microsurgical blade made a cut in the zona

Production of Experimental Chimeras in Livestock by Blastocyst Injectiontact with each other and allowed to aggregate into a single embryo. The chimeric embryos were allowed to develop to the blastocyst stage and then transferred to suitable recipients. The ability to readily produce large numbers of whole body chimeras proved to be a valuable tool in the study of embry

Molecular Approaches to Vaccines vaccines can cause acute or slowly progressive diseases in immunodeficient individuals or in alternate animal hosts. Live poliovirus vaccine produces a few cases each year of paralytic polio in vaccinees or their contacts (91). Even so-called killed virus vaccines can contain infectious particles.

Combining genetic manipulation with the well-established biotechnologies of semen and embryo preservation has increased man’s options for preserving genetic resources that at present seem to be dwindling through the loss of animal species in a technology-dominated world.
