In contrast to wild type, the number of Pkd2ko67 / Pkd2MB06703 sperm that enter the distal seminal receptacle (DSR) vary greatly on an individual basis and the average number of sperm stored per female per mating is only 5.5. Only 4.4 F1 progeny are produced per female from matings to these mutant males.
Pkd2ko67/Pkd2MB06703, lobolobo/loboMB00722 has male semi-sterile phenotype
Sperm from lobolobo/loboMB00722; Pkd2ko67 / Pkd2MB06703 double mutants are motile, are produced in large numbers and can enter the uterus as normal. However, in contrast to wild type, the number of sperm that enter the distal seminal receptacle (DSR) vary greatly on an individual basis and the average number of sperm stored per female per mating is only 2.4. Only 2.9 F1 progeny are produced per female from matings to these double-mutant males.
Stored sperm from lobolobo/loboMB00722; Pkd2ko67 / Pkd2MB06703 double mutant males can exit the distal seminal receptacle and fertilize the egg.
