Greengram (Vigna radiata (L.) Wilczek) is one of the highly consumed legumes and has ability to withstand wide environmental conditions. Sixty greengram genotypes were evaluated for genetic relatedness with 11 quantitative traits viz., days 50 per cent flowering, maturity, plant height, number primary branches plant, clusters pods cluster, seeds pod, pod length, hundred seed weight single yield...

The objective of the present study was to determine the presence of genotype by environment interaction (G × E) and to characterize the phenotypic plasticity of birth weight (BW), weaning weight (WW), postweaning weight gain (PWG) and yearling scrotal circumference (SC) in composite beef cattle using the reaction norms model with unknown covariate. The animals were born between 1995 and 2008 on...

Traditional family, twin and adoption studies have shown consistently that psychopathology and cognitive traits are familial and heritable. High heritability estimates have led to the conclusion that genetic factors make a substantial contribution to risk of many mental disorders and have fuelled the search for DNA variants associated with psychopathology and cognitive traits. Molecular genetic...

A divergent selection experiment for serum IGF-I concentration was established in 1989 at the Eastern Agricultural Research Station located in Belle Valley, Ohio. One hundred spring-calving (50 high line and 50 low line) and 100 fall-calving (50 high line and 50 low line) cows with unknown IGF-I concentrations were randomly assigned to the 2 divergent selection lines. Results of this study incl...

Background: Forty two crosses involving seven lines and six testers were studied for economically important yield contributing quality traits to test the magnitude of genetic components diversity. Formulation efficient breeding methodology is possible by targeting architecture genotypes. Methods: The systematic programme involves generating variability besides sorting off diverse genotypes util...

A study was conducted to estimate heritabilities of, and genetic correlations among, body weight (WT) and testicular measurements - scrotal circumference (SC), testicular diameter (TD), testicular length (TL) and epididymal diameter (ED) - in ram lambs between 6, 9 and 12 months old, and relationship of the testicular traits with age at puberty in ewe lambs (AP). Two fat-tailed sheep breeds, th...

What in your view is the distinguishing feature of developmental biology with respect to other natural sciences? It is the source of causality, the genome. Developmental biology differs from other sciences, physics, for example, most profoundly because of the organizing role of the primary informational content of the genome. The genomes of animals are the unique products of a billion years of ...

the fact that life styles and personal interests, aggregate within families suggests that shared environment in addition to shared bioligical factors could play a role in determining the phenotypic similarity of idividuals living in the same household. it is a major concern of cardiovascular epidemiologists to know how much of the familial aggregation of blood pressure is attributable to shared...

Estimates of direct and maternal genetic parameters in beef cattle were obtained with a random regression model with a linear spline function (SFM) and were compared with those obtained by a multitrait model (MTM). Weight data of 18,900 Gelbvieh calves were used, of which 100, 75, and 17% had birth (BWT), weaning (WWT), and yearling (YWT) weights, respectively. The MTM analysis was conducted wi...

Fifty two genotypes of Indian bean were examined for the genetic variability parameters and trait correlation 11 yield contributing traits in F5 progenies. Analysis revealed that these had a considerable level diversity. The magnitude GCV PCV was high seed per plant, which indicated potential selection based enhancement. values moderate pod weight, pods width length. High heritability along wit...
