homogonicadj.

/hɒməʊˈɡɒnɪk/

Etymology: < homo- comb. form + Greek -γονος generating, γόνος offspring + -ic suffix.

Biology.

Applied to a life cycle of certain nematodes in which the offspring of a parasitic generation themselves develop into parasites, without the intervention of a free-living generation; also applied to organisms reproducing by such a cycle. Opposed to heterogonic adj. 2.

1926 J. H. Sandground in Amer. Jrnl. Hygiene VI. 338 In the genus Strongyloides [of nematodes] heterogony may be involved in the life-cycle, but in many instances there is only one multiplicative generation and this mode of development has been called direct or, if we may introduce a new term to express this, homogonic in contradistinction to heterogonic or indirect.

1939 Amer. Jrnl. Hygiene 30 d. 15 In those Strongyloides infections where both modes of larval development are commonly encountered, there is little constancy in the daily yields of heterogonic, i.e., indirect or free-living adult, in contrast to homogonic, or direct, progeny.

1951 L. H. Hyman Invertebrates III. xiii. 307 It is probable that any species of Rhabdias may employ either the homogonic or heterogonic type of life cycle.

1968 N. D. Levine Nematode Parasites ii. 75/1 Absence of food, too, led to homogonic development.

homoˈgonically adv. by means of a homogonic life cycle.

1938 Amer. Jrnl. Hygiene 28 224 The production of these two types of progeny was related to the age of the single, homogonically derived parasite.
