Severe congenital neutropenia (SCN) is an exceptionally rare genetic disorder associated with life-threatening bacterial infections. Among the several genetic variations related to SCN, heterozygous mutations in the ELANE gene encoding neutrophil elastase account for approximately 40 - 55% of the genetic causes.

Cathelicidins include antimicrobial peptides (AMPs) and are involved in the innate immune defense against infections in mammals. Polymorphisms in the DNA sequence of cathelicidin genes could be relevant to inherited variations of host innate immunity, adaptation, and pathogen resistance. This study aims to investigate the sequence polymorphism of cathelicidin genes including CATHL2 and CATHL4 from local indigenous yellow cattle breeds of Vietnam.

In the present study, the components of genetic variation were studied in AN (Arka Nidhi) and SN (Singh Nath) for quantitative characters. The estimates of both additive and dominance components were significant for all the characters except days to 50 per cent flowering, fruit diameter, number of branches per plant and pedicel length. Epistasis (i) and (j+l) type was significant in all the traits except except fruit diameter (cm).

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.

The present investigation was carried out to estimate phenotypic and genotypic coefficient of variation, heritability (broad sense), genetic advance and genetic gain for 15 quantitative traits in 21 different genotypes of Garden pea during Rabi2011-12 at Vegetable Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi (U. P.). Significant differences among the genotypes were observed for all the characters under study.

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.

Guava (Psidium guajava L; Myrtaceae) popularly known as “apple of tropics” is an important fruit crop of India. It is largely a self-pollinated crop, but crosspollination also does occur. This results in a large variability in the seedling population. Among cultivars, substantial variation exists in terms of growth pattern, yielding behavior, fruit characters (peel, shape etc.) and physio-chemical composition, aroma, pulp to seed ratio, seed characters. Assessment of variability can be achieved through morphological characters, chemical composition and by biotechnological tools.

The experiment was conducted in experimental Farm, Regional Research Station, Anand Agricultural University from July to November 2018toestimate the extent of variability present in rice genotypes with respect to yield and its component traits. The estimates of genotypic and phenotypic variances for the characters like plant height, effective tillers per plant, number of grains per panicle, grain yield per plant, straw yield per plant, harvest index and 1000 grain weight, genotypic variance contributed larger in phenotypic variance.

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.

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....
