As a Marie Curie fellow at UCL I am interested in the
evolution and sexual selection of stalk eyed flies (Diopsidae) and I
am trying to answer questions by studying the genetics and behaviour
Evidence from the field and laboratory shows that females
prefer to mate with males that have the largest eyespan. It is thought
that male eyespan acts as a signal of male genetic quality, as this
sexually exaggerated trait exhibits heightened condition dependent expression.
Teleopsis dalmanni is emerging as one of the key model systems
for studying sexual selection driven by female mate preference and features
as a key species in many popular textbooks. I will measure and map genetic
variation in the stalk-eyed fly, T. dalmanni. My goal is to
map genetic variation in male eyespan of stalk-eyed flies across natural
populations. I will initially concentrate on a population from the Gombak
valley in Malaysia as this was the source for a laboratory based study
of genetic variation. I will also investigate a distantly related population
of T. dalmanni, to establish whether the same set of genetic
loci contribute to genetic variation in eyespan in an evolutionarily
divergent population. I will cross individuals from these two natural
populations to establish which quantitative genetic loci have contributed
to evolutionary divergence between populations.
