1. Inferencias geneticas na producao e qualidade de tomateiro sob cruzamento dialelico.
Inferencias geneticas sobre o desempenho de cinco cultivares de tomateiro (Angela I. 5100, Floradade, IPA-05, Jumbo AG-592 e Santa Clara) e seus p(p-1)/2 hibridos dialelicos foram obtidas com base em tres caracteristicas de producao e quatro caracteristicas relacionadas a qualidade dos frutos, empregando-se a metodologia de Hayman (1954). Os resultados evide

2. Emprego do BLUP/REML na avaliação genética de linhagens elites de milho-pipoca / The use of BLUP/REML for genetic evaluation of popcorn elite lines
Em programas de melhoramento é importante o uso de alternativas viáveis para redução de custos e tempo nas avaliações de populações, aliadas ao uso de metodologias estatísticas adequadas, que aproveitem ao máximo as informações disponíveis. Neste contexto, o presente trabalho teve como objetivos: i) estudar o controle genético da capacidade de

3. Human Diallelic Insertion/Deletion Polymorphisms
We report the identification and characterization of 2,000 human diallelic insertion/deletion polymorphisms (indels) distributed throughout the human genome. Candidate indels were identified by comparison of overlapping genomic or cDNA sequences. Average confirmation rate for indels with a ⩾2-nt allele-length difference was 58%, but the confirmation rate f

4. Genetic Fine Structure Analysis of the AMYLOSE-EXTENDER Locus in ZEA MAYS L
On the basis of interallelic recombination frequencies measured in diallelic crosses of the 5 amylose-extender alleles in maize, ae, B1, B3, M2 and i1, it was possible to construct a unique linear genetic map ordering all 5 alleles within the locus. The reciprocal diallelic crosses each gave comparable frequency estimates. The relative order is ae, i1, B3, B

5. Single-well genotyping of diallelic sequence variations by a two-color ELISA-based oligonucleotide ligation assay.
Single nucleotide substitutions and unique insertions/deletions are the most common form of DNA sequence variation and disease-causing mutation in the human genome. Because of the biological and medical importance of these variations, a wide array of methods have been developed for their typing. We have applied an approach that combines the amplification of

6. Highly accurate analysis of heterozygous loci bysingle cell PCR.
Single cell PCR is a powerful method for determining the genetic properties of individual cells. In the instance of heterozygous loci, however, preferential amplification of one allele can lead to allele drop out (ADO) of the other allele. Fortunately ADO does not occur in all amplifications, and is usually random when it does occur, with both alleles being

7. On Some Models of Fertility Selection
Additive, multiplicative and symmetric models of fertility controlled by one diallelic gene are studied. For the completely symmetric fertility system a complete equilibrium and local stability analysis is possible. Contrary to previous conjectures, asymmetric equilibria can be stable. Conditions are derived under which a multiplicative model can be regarded

8. Angiotensinogen gene and hypertension in Chinese.
The renin-angiotensin system plays a major role in regulating blood pressure and maintaining electrolyte and volume homeostasis. Previously, the angiotensinogen gene, which encodes the key substrate for renin within this system, has been reported linked to and associated with essential hypertension in White Europeans, African-Caribbeans, and Japanese. Theref

9. Numerical Analysis of Weak Random Drift in a Cline
The equilibrium state of a diffusion model for weak random genetic drift in a cline is analyzed numerically. The monoecious organism occupies an unbounded linear habitat with constant, uniform population density. Migration is homogeneous, symmetric, and independent of genotype. A single diallelic locus with a step environment is investigated in the absence o

10. Genetic Bit Analysis: a solid phase method for typing single nucleotide polymorphisms.
A new method for typing single nucleotide polymorphisms in DNA is described. In this method, specific fragments of genomic DNA containing the polymorphic site(s) are first amplified by the polymerase chain reaction (PCR) using one regular and one phosphorothioate-modified primer. The double-stranded PCR product is rendered single-stranded by treatment with t

11. Random genetic drift in a cline
A diffusion model is derived for random genetic drift in a cline. The monoecious organism occupies an unbounded linear habitat with constant, uniform population density. Migration is homogeneous, symmetric, and independent of genotype. The analysis applies to a single diallelic locus without dominance or mutation. Assuming that Hardy—Weinberg proportions o

12. A 3' splice site mutation in the thyroglobulin gene responsible for congenital goiter with hypothyroidism.
A case of congenital goiter with defective thyroglobulin synthesis has been studied in molecular terms. The patient is the fifth of a kindred of six, three of which have a goiter. The parents are first cousins. Segregation of thyroglobulin alleles in the family was studied by Southern blotting with a probe revealing a diallelic restriction fragment length po
