HIGHER FEMALE THAN MALE RECOMBINATION RATES IN A MARSUPIAL MAMMAL, THE TAMMAR WALLABY (MACROPUS-EUGENII)

Previous work has shown that females have lower recombination rates th an males in two distantly related marsupial species, an American didel phid and an Australian dasyurid. We report here that the tammar wallab y (Macropus eugenii), which belongs to a third major group, has higher female recombination rates in two linked pairs. The nature of the sex differences in recombination rates in this species is thus similar to the situation in eutherian mammals.
