seminal duct वाक्य

The spermatophore consists of two parts : a large gelatinous mass, and a smaller seminal duct containing the sperm.
When this tip inflates, species specific ridges and spines flare up that match up with the walls of the male s seminal duct.
The two are linked internally by a seminal duct . ( In more basal lineages there is one cloaca, or later, two openings and an external sperm canal . ) Of the early lineages of Ditrysia, Gracillarioidea and Gelechioidea are mostly leaf miners, but more recent lineages feed externally.
