polymeryn.

Brit.

/pəˈlɪm(ə)ri/,

/pɒˈlɪm(ə)ri/, U.S.

/pəˈlɪm(ə)ri/

Forms: 1900s– polymeria (rare), 1900s– polymery.

Origin: Formed within English, by compounding. Etymons: poly- comb. form, -mery comb. form.

Etymology: < poly- comb. form + -mery comb. form, after polymerous adj.¹ Compare Hellenistic Greek πολυμέρεια the condition of consisting of many parts.In sense 2 after German Polymerie (A. Lang 1911, in Zeitschr. f. induktive Abstammungs- u. Vererbungslehre 5 113).

1. Botany. The property of consisting of many parts or segments, or more than the usual number.

1910 Missouri Bot. Garden Ann. Rep. 175 Several interesting ‘abnormalities’ of structure. These include virescence or frondescence and polymery of the flowers, tricotyly and variegation of leaves.

1970 Amer. Jrnl. Bot. 57 749/2 Cronquist suggested that ancestral Araliaceae had 5-merous flowers and that polymery arose through secondary increases in the floral whorls.

1997 Internat. Jrnl. Plant Sci. 158 s6 The very high degree of polymery in the androecium, as observed in Annona montana (up to 2000 stamens).., can be regarded as advanced within the family.

2. Genetics. The phenomenon whereby a number of non-allelic genes at different loci (which may be polygenes) can act together to produce a single effect.

1914 Zeitschr. f. induktive Abstammungs- u.

Johannsen (1913) suggests that..[this term] be retained..for the phenomenon in general.

1927 Zeitschr. f. Induktive Abstammungs- u. Vererbungslehre 43 331 The discovery of polygenous characters, especially the phenomenon of polymeria discovered by Nilsson Ehle, made it necessary to recognize, that at least a great many characters are determined not by one but by several and even many genes.

1948 H. P. Riley Introd. Genetics & Cytogenetics xxii. 353 Although the multiple factor hypothesis (or theory of polymery) seems to be a very handy explanation for the inheritance of quantitative characters, it has frequently been questioned.
