Birth, death, pair formation, and separation are described by a system of three nonlinear homogeneous ordinary differential equations. The qualitative properties of the system are investigated, in particular the conditions for existence and global stability of the bisexual state.

✦ Synopsis
The standard model for pair formation is generalized to include a maturation period. This model in the form of three coupled delay equations is a special case of the general age-structured model for a two-sex population. The exact conditions for the existence of an exponential (persistent) two-sex solution are derived. It is shown that this solution is unique and locally stable. In order to achieve these results the theory of homogeneous differential equations is extended to a class of homogeneous delay equations.

In the use of age structured population models for agricultural applications such as the modeling of crop-pest interactions it is often essential that the model take into account the distribution in maturation rates present in some or all of the populations. The traditional method for incorporating
Conditions on the vital rates of a two-sex population are presented which imply the existence or nonexistence of exponentially growing persistent age-distributions.
## Abstract We present a base‐pairing model of oligonucleotide duplex formation and show in detail its equivalence to the nearest‐neighbor dimer methods from fits to free energy of duplex formation data for short DNA–DNA and DNA–RNA hybrids containing only Watson–Crick pairs. For completeness, the
