Hologynic Heredity.
Sex-linked characters in man are well known; they are all pathological characters, so far as known; they are transmitted according to the same laws as the sex-linked characters in the little fruit-fly (Drosophila) and explained in the same manner by means of the sex chromosome. I propose the name “diagynic heredity” for this kind of heredity, as the sex-linked character is transmitted from male...

Bracon admotus Papp, 2000, and three species of the genus Habrobracon Ashmead, 1895, Habrobracon concolorans (Marshall, 1900), Habrobracon hebetor (Say, 1836) and Habrobracon pillerianae Fischer, 1980, were obtained from the larvae of Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera, Tortricidae) feeding on Daphne gnidium Linnaeus, 1753 (Thymelaeaceae) in the natural reserve of Migli...
متن کاملThe Determination of Sex in Habrobracon.
In short, testis size in F1 hybrids is determined by an interaction between the chromosome complement and the cytoplasm. We are dealing either with a real cytoplasmic effect (determination by the intrinsic properties of the cytoplasm, independent of the chromosomes it carries or carried), or with a maternal effect (determination of the properties of the cytoplasm by those of the chromosomes it ...
متن کاملA narrow hybrid zone between two Cottus species in Wills Creek, Potomac drainage.
We describe a narrow hybrid zone between the mottled sculpin (Cottus b. bairdi) and the Blue Ridge sculpin (C. caeruleomentum). Seven characters (dorsal fin rays, pectoral fin rays, caudal base band condition, male spawning coloration, and one frequency and two fixed allozyme differences) distinguish the two taxa in the hybrid zone. C. caeruleomentum and C. b. bairdi diverged in these character...
