In this talk I will present some examples of previous work, as well as
some current projects. Genetic work on the long-tailed macaques in Ketambe
was initially based on protein analysis. The analysis of relatively
variable proteins allowed for population genetic analysis with sufficient
resolution to calculate relatedness, but not always to determine paternity
through exclusion. For this latter task DNA multi-locus fingerprinting was
included. The result provided good data on reproductive success and
allowed for a re-interpretation of the sexual strategies of the macaques.
With the advent of microsatellite analysis using PCR, we were able to
carry out similar work on wild orang-utans with non-invasive sampling
techniques. The results allowed us to analyze the alternative reproductive
strategies of the males, for which data on both paternity as well as
relatedness amongst males were required. In a current project on marmosets
we are classifying individuals in different personality types. The purpose
of the investigation is to investigate the degree to which personality
types are prevalent in particular family lines. Ultimately we want to
investigate genes responsible for the observed differences in personality.
