paedogeneticadj.

Brit.

/ˌpiːdə(ʊ)dʒᵻˈnɛtɪk/, U.S.

/ˈˌpidədʒəˈnɛdɪk/

Forms: 1800s– paedogenetic, 1900s– pedogenetic (see note below).

Origin: Formed within English, by compounding. Etymons: paedo- comb. form, -genetic comb. form.

Etymology: < paedo- comb. form + -genetic comb. form, after paedogenesis n.The form pedogenetic is uncommon, even in U.S. usage, perhaps because of the potential confusion with pedogenetic adj.; compare paedogenesis n.

Biology.

1. Relating to or characterized by (parthenogenetic) reproduction occurring in a larval or immature form. Cf. paedogenesis n. 1.

1992 Amer. Naturalist 139 985 Many of the most outstanding polyphenisms in metazoans are found in those few, unrelated taxa in which cyclical parthenogenesis has been established, particularly certain rotifers, the daphnids, the aphids, and the paedogenetic cecidomyiids.

2. Relating to or characterized by the presence of juvenile or larval characteristics in an adult organism; paedomorphic. Also: relating to or characterized by precocious sexual reproduction in a juvenile or larval form. Cf. paedogenesis n. 2.
