1889 Q. Jrnl. Microsc. Sci. 30 203 In another deviation, which Flemming describes as the ‘homöotypic Form’ (that is to say, ‘a form more like the usual one than the one just described, which he names “heterotypic”’), it would appear..that longitudinal splitting may be entirely absent.
1931 W. Shumway Textbk. Gen. Biol. vi. 149 The first maturation division is sometimes called the heterotypic division because of its novel features of synapsis and tetrad-formation.
1969 W. V. Brown & E. M. Bertke Textbk. Cytol. xx. 436 Previously, meiosis I was called the heterotypic mitosis, implying that it is an atypical mitosis, which it certainly is; and meiosis II was called the homeotypic mitosis, implying that it is a fairly typical mitotic division, which it is.

1888 Jrnl. Royal Microsc. Soc. 553 He [sc. Flemming] finds that these cells [sc. spermatocytes] exhibit a remarkable dimorphism of mitosis; in the heterotypical form the chromatic formations exhibit metakinesis. The two forms, the other of which may be called homœotypical, are sometimes found together.

The genus Microporella as well as the genus Escharina may serve as examples of such a variable development of the two heterozoœcial forms.

1909 G. M. R. Levinsen Cheilostomatous Bryozoa 46 We can distinguish between four main forms of individuals (Bryozooids):..Heterozoœcia (Heterozooids), which have no intestinal canal, and at most have a trace of a polypide in a small cell-body, furnished with a circle of fine bristles. The chamber contains a strong muscular apparatus for moving the operculum.
1959 L. H. Hyman Invertebrates V. xx. 325 Other types of zooids are termed collectively heterozooids and are characterized by the reduction of the polypide, which loses its nutritive and reproductive function.
