A conditional virginator stock was made by jumping P{hs-hid} onto the Dp(2;Y)G modified Y. The stock produces few males due to the duplication, but is generally healthy despite this (may cause problems when combined with other backgrounds). The modified Y also causes some increased non-disjunction so incidence of XO males is increased. As these are sterile, they do not interfere with the virginator aspects of the stock.
