^a Number of animals assayed.
^b Scored as animals that transfer sperm without tonic contraction of spicules in the vulva.
^c Percentage altered is the number of animals with altered transfer divided by the total number of animals tested. Altered transfer for wild type includes premature transfer and no transfer. Altered transfer for sy671 includes premature transfer and wild-type transfer.
^d Wild type is strain PS3696, plg-1(e2001); him-5(e1490).
