Phylum reproduce how?

Answer 1

First, there is no Phylum Diplododa. Diplododa (millipedes) is a Class within the Phylum Arthropoda. Second, Millipedes show a diversity of mating styles and structures. In the basal order Polyxenida, males deposit spermatophores that are subsequently picked up by females. In all other millipede groups, males possess one or two pairs of modified legs called gonopods which are used to transfer sperm to the female during copulation. The location of the gonopods differs between groups: in males of the Pentazonia they are located at the rear of the body and known as telopods, while in Helminthomorpha - the vast majority of species - they are located on the 7th body segment A few species are parthenogenetic, having few, if any, males.
