Genic Heterozygosity and Variation in Permanent Translocation Heterozygotes of the OENOTHERA BIENNIS Complex.
Genic heterozygosity and variation were studied in the permanent translocation heterozygotes Oenothera biennis I, Oe. biennis II, Oe. biennis III, Oe. strigosa, Oe. parviflora I, Oe. parviflora II, and in the related bivalent formers Oe. argillicola and Oe. hookeri. From variation at 20 enzyme loci, we find that translocation heterozygosity for the entire chromosome complex is accompanied by on...
متن کاملProtein polymorphism and genic heterozygosity in a population of the permanent translocation heterozygote, Oenothera biennis.
Genic allozyme polymorphism and heterozygosity was studied in a large population of the evening primrose, Oenothera biennis, growing in North Haven, Connecticut. This species is a permanent structural heterozygote for the entire complement of 14 chromosomes, and is thus capable of accumulating and maintaining genic heterozygosity. A total of 11 protein species were examined, and these were judg...

متن کاملPERMANENT GENETIC RESOURCES: Isolation and characterization of polymorphic microsatellite loci in common evening primrose (Oenothera biennis).
We developed nine polymorphic microsatellite loci for evening primrose (Oenothera biennis). These loci have two to 18 alleles per locus and observed heterozygosities ranging from 0 to 0.879 in a sample of 34 individuals. In a pattern consistent with the functionally asexual reproductive system of this species, 17/36 pairs of loci revealed significant linkage disequilibrium and three loci showed...
متن کاملThe Incompatibility Mechanism of the Biennis Group I Races of Oenothera.
EARLY all of the North American euoenotheras east of the Rocky Mountains Nremain heterozygous generation after generation even though they have the self-pollinating habit. A specialized cytogenetic mechanism involving multiple reciprocal translocations and a balanced lethal system accounts for this paradox. These Oenotheras possess 14 chromosomes of which each set of seven, because of reciproca...
