The mating efficiency of folt-1 knockout males compared to folt-1/+ heterozygous males. The activity of single males confined with 10 wild type hermaphrodites was observed at five minute intervals for an hour. Homozygous folt-1 knockout males were observed to be alone a greater percentage of our observations, and to be mating much less than were folt-1/+ heterozygotes.
