Male accessory gland secretions in hybrids of Drosophila nasuta nasuta and D. n. albomicans neither show luxuriance nor breakdown.
Male accessory gland secretions, which have a role to play in reproduction have been investigated. The number of cells that make up the gland, the quantity of secretions synthesized and the influence of these secretions on fecundity of the female have been studied in D. n. nasuta, D. n. albomicans and their F1 progeny. The results revealed that the hybrid males show a trend towards D. n. nasuta in the synthesis of male accessory gland proteins and the fecundity of the female is influenced more by its genetic constitution rather than the quantity of accessory gland secretions.
