Abstract
Male-haploidy has independently evolved several times in different
phylogenetic groups and has led to various extant lineages in the
insects, Arachnida and Rotifera. Although the stability of male-haploidy
as an evolutionary strategy is not well understood, various theories
address the invasion of male-haploidy in diploid populations. Here two
of these theories: (i) the maternal transmission hypothesis (MTH) and
(ii) the deleterious mutation hypothesis (DMH), are re-investigated with
an agent-based model to understand the role of genetic drift as a
mechanism facilitating the spread of male-haploidy. These two hypotheses
are analysed separately and comparatively, and the results suggest
dominance of the MTH. In addition, comparison of the stochastic results
to deterministic results using the same model structure shows how
genetic drift can enhance the parameter space where male-haploidy can be
expected to invade.
