Genetic variation

Polymerase Chain Reaction is widely held as one of the most important inventions of the 20th century in molecular biology. Small amounts of the genetic material can now be amplified to be able to a identify, manipulate DNA, detect infectious organisms, including the viruses that cause AIDS, hepatitis, tuberculosis, detect genetic variations, including mutations, in human genes and numerous other tasks.

The present investigation was under taken with the objectives to estimate genetic variability, heritability and genetic advance for yield and yield contributing components of cucumber. The experimental materials for this investigation were fourteen genotypes of cucumber consisting of parthenocarpic, gynoecious and monecious germplasms crossed in line × tester mating design produced thirty three hybrids (F1). Thirty three F1 crosses along with their parents were evaluated in two environments viz.

In order compute genetic variability, heritability and genetic advance expressed as per cent of mean, an investigation was carried out with 79 plants of F2 population of MFC-09-12 × PGCP-12 and 90 plants of F2population of MFC-08-14 × PL-3 in cowpea. Considerably high amount of variability was observed for the thirteen quantitative and qualitative characters under study.

Understanding the genetic complexity of traits is an important objective of small grain temperate cereals yield and adaptation improvements. Bi-parental quantitative trait loci (QTL) linkage mapping is a powerful method to identify genetic regions that co-segregate in the trait of interest within the research population. However, recently, association or linkage disequilibrium (LD) mapping using a genome-wide association study (GWAS) became an approach for unraveling the molecular genetic basis underlying the natural phenotypic variation.

Humanb2 -glycoprotein I (b2 GPI), also known as apolipo-protein H, has been implicated in haemostasis and the pro-duction ofanti-phospholipid antibodies. There is a wide range ofinterindividual variation in b2GPI plasma levels that is thought to be under genetic control, but itsmolecular basis remains unknown. To understand the genetic basis of b2GPI variation, we analyzed the 5¢ flanking region ofthe b2GPIgene for mutation detection by DHPLC and identi-fied a point mutation at the transcriptional initiation site ()1CfiA) with a carrier frequency of 12.1%. ...

Mitochondrial fatty acid oxidation deficiencies are due to genetic defects in enzymes of fatty acidb-oxidation and transport proteins.Genetic defects have been identified in most of the genes where nearly all types of sequence vari-ations (mutation types) have beenassociatedwithdisease.In this paper, we will discuss the effects of the various types of sequence variations encountered and review current know-ledge regarding the genotype–phenotype relationship, espe-cially in patients with acyl-CoA dehydrogenase deficiencies where sufficient material exists for a meaningful discussion....

The treatment of AIDS remains a serious challenge owing to high genetic variation of Human Immunodeficiency Virus type 1 (HIV-1). The use of different antiretroviral drugs (ARV) is significantly limited by severe side-effects that further compromise the quality of life of the AIDS patient. In the present study, we have evaluated a liposome system for the delivery of nevirapine, a hydrophobic non-nucleoside reverse transcriptase inhibitor. Liposomes were prepared from egg phospholipids using thin film hydration.
