matroclinous, a. Biol.|mætrəʊˈklaɪnəs|
[f. L. mātr-, māter mother + Gr. κλίν-ειν to lean + -ous.]
Resembling the female rather than the male parent; involving or possessing a tendency to inherit a character or characters from the female parent only. So ˈmatrocliny, matroclinous inheritance.
1913Jrnl. Exper. Zoöl. XV. 587 Morgan has explained the case of criss-cross inheritance on the ground that the X-chromosome is the carrier of all sex linked factors. The sons are matroclinous because they receive their unpaired chromosome directly from the mother, and must show all the sex linked characters which she showed. 1917Genetics II. 247 But even if one hybrid should be judged to indicate patrocliny in one cross, the same hybrid appears in the reciprocal cross where it would be a case of matrocliny for the same hybrid. 1925C. C. Hurst Exper. in Genetics xxxviii. 535 Gametic chromosomes, male and female, are either equal with 7–14–21 or 28 each, or unequal and matroclinous with a maternal bias in the ratio of 1·5–2–3–4 or 5:1. 1939Nature 14 Jan. 81/2 To account for the purely matroclinous inheritance, the following explanation is suggested. The eggs of M. formosa are fertilized by the other two species, but the paternal chromosomes remain inactive. 1961A. Müntzing Genetic Res. xxvi. 257/1 F. von Wettstein..observed that this matrocliny was clearly noticeable also in [the] F2. 1968R. C. King Dict. Genetics 149 In Drosophila the daughters produced by attached-X females are matroclinous in terms of their sex-linked genes. |
