Chorionic gonadatrophin (CG) is an integral part of the complex
endocrinology of pregnancy in primates. This glycoprotein hormone is
utilized as a biochemical marker for pregnancy in many species of
primates. Part I of this thesis is directed towards the construction
of a general inductive model of chorionic gonadatrophin patterns which
will indicate regularities of occurence and overall relationships.
This model propoeses a general continuum of CG production which
corresponds to phylogenetic expectations as illustrated by antigenic
similarities and similarities in CC patterns across primate species
and families. Also discussed is an apparent divergence of CG role and
function in two cercopithecine genera. This discussion of comparative
aspects of CG is an attempt to add insight into an important aspect
of the primate reproductive process. Part II utilizes this comparative
information to construct a guide which provides a practical
application for the use of CG in breeding programs.
