Heterozygosis and genetic recombination in herpes simplex type 1 virus
Virology, 1977Abstract Two- and three-factor crosses with temperature-sensitive (ts) and syncytial plaque morphology (syn) mutants of herpes simplex type 1 virus have been used to study the possible role of syn-syn+ mixed plaque-forming virus in genetic recombination.

Structural heterozygosis in man: analysis of two families
Annals of Human Genetics, 1962SummaryTwo families are described in each of which the father is presumed to have an autosomal reciprocal translocation as a result of which both children in one family, and one of three children in the other, are grossly abnormal. The reciprocal translocations are probably between chromosomes nos. 9 and 4 in the first family, and chromosomes nos.

Electrophoretic demonstration of heterozygosis in hereditary pyruvate kinase deficiency
Human Genetics, 1979The defective PK variant of a patient with a severe form of hemolytic anemia was characterized by its inability to undergo a normal 'proteolytic maturation.' In obligatory heterozygotes it could be proved that red cells contained different PK species, some of them sensitive and the others partially resistant to the action of trypsin.

Polyembryony, heterozygosis and chimeras in citrus
Hilgardia, 1926Abstract does not appear. First page follows. Introduction The genus Citrus is characterized by remarkable genetic variability, both in seed reproduction and within clonal varieties. An F1 hybrid progeny usually exhibits great genetic diversity (Swingle, 1913a), suggesting the F2 generation from a cross between races differing in ...

The penultimate aim of any breeding programme is to derive a clone with enhanced dry rubber yield (g tree−1 tap−1) and, if possible, with improved secondary attributes like resistance to diseases and high/low temperature stresses. The efficient use of the available genetic variability in the form of clones is further augmented through bud grafting ...

Severe prekallikrein deficiency due to a compound heterozygosis in the KLKB1-gene
Hämostaseologie, 2009SummaryA 14 year old boy was referred to us for a detailed coagulation study because a previously performed aPTT has been found prolonged. The boy had no history of bleeding symptoms and also the family history was negative for bleeding or thrombotic events. The aPTT in the patient was 96 s (reference range: 24–36 s), prothrombin time and thrombin time

Structural heterozygosis at genes IL V2 and IL V5 in Saccharomyces carlsbergensiss
Current Genetics, 1987Chromosomes XII and XIII of a Saccharomyces carlsbergensis brewing strain were analysed after their transfer into Saccharomyces cerevisiae by kar1-mediated single chromosome transfer. The lager yeast was found to be heterozygous for the isoleucine-valine biosynthesis genes IL V2 (encoding acetohydroxy acid synthase) and IL V5 (encoding acetohydroxy ...

Heterosis and Heterozygosis in Pearl Millet Forage Production1
Crop Science, 1968Well‐established inbred lines of pearl millet, Pennisetum typhoides, were used to develop seed lots with 0, 50, 75, and 100% heterozygosity. Total annual forage yields (three or four cuttings per year) from drilled plots of these seed lots in lattice‐square experiments supplied the data considered.

[Heterozygosis H63D in patients with steatohepatitis and chronic hepatitis C].
La Clinica terapeutica, 2007Classic hereditary hemochromatosis is an autosomal recessive iron-overload disorder associated with mutation of the HFE gene. The homozygous genetic defect predisposes to a chain of events that may culminate in severe damage in multiple organs. Pathologic implications of heterozygous defect are still questionable; in fact since these individuals may ...

The amount of heterozygosis to be expected in an approximately pure line
Journal of Genetics, 1936Heterozygosis in an approximately pure line is due to two causes. On the one hand, part of the heterozygosis of the original ancestors remains for some generations. Owing to linkage a few zygotes may have comparatively large heterozygous segments, but most of them are completely homozygous.
