Abstract
At meiosis in female Trichosurus vulpecula there are fewer chiasmata per cell and fewer interstitial chiasmata than are observed in male T. vulpecula. These observations suggest that recombination in the female will be less than that observed in the male; however, this difference between the sexes will not be as great as that previously described in other marsupial species.
