Correlation and heritability
-
Associations of low lung function with features of poor cardio-metabolic health have been reported. It is, however, unclear whether these co-morbidities reflect causal associations, shared genetic heritability or are confounded by environmental factors.

Irritable bowel syndrome (IBS) often co-occurs with psychiatric and gastrointestinal disorders. A recent genome-wide association study (GWAS) identified several genetic risk variants for IBS. However, most of the heritability remains unidentified, and the genetic overlap with psychiatric and somatic disorders is not quantified beyond genome-wide genetic correlations.

Pulmonary arterial hypertension (PAH) is a rare vascular disorder characterized by a capillary wedge pressure ≤ 15 mmHg and a mean pulmonary arterial pressure ≥ 25 mmHg at rest. PAH can be idiopathic, heritable or associated with other conditions.

Persons living with HIV/AIDS (PLWHA) are at an increased risk of suicide. Increased suicidal risk is a predictor of future attempted and completed suicides and has been associated with poor quality of life and poor adherence with antiretroviral therapy. Clinical risk factors have low predictive value for suicide, hence the interest in potential neurobiological correlates and specific heritable markers of suicide vulnerability.

Correlated genetic response in survival to selection for high growth has not been reported in giant freshwater prawn (GFP) (Macrobrachium rosenbergii). The main aim of this study was to measure genetic changes and estimate heritability for this character (survival rate) and its genetic associations with body traits in a GFP population selected over eight generations from 2008 to 2015.

Most traits targeted in the genetic improvement of hop are quantitative in nature. Improvement based on selection of these traits requires a comprehensive understanding of their inheritance. This study estimated quantitative genetic parameters for 20 traits related to three key objectives for the genetic improvement of hop: cone chemistry, cone yield and agronomic characteristics.

Semen traits are important for the widespread use of superior bulls. Thus, the objective of this study was to estimate the heritability of five semen traits, ejaculate volume (VE), progressive sperm motility (SM), sperm concentration (SC), number of sperm (NSP), and number of progressive motile sperm (NMSP), and their genetic correlations (rg).

Transgenerational epigenetic inheritance has been posited as a possible contributor to the observed heritability of metabolic syndrome (MetS). Yet the extent to which estimates of epigenetic inheritance for DNA methylation sites are inflated by environmental and genetic covariance within families is still unclear.

The high narrow sense heritability of carcass traits suggests that the underlying additive genetic potential of an individual should be strongly correlated with both animal carcass quality and quantity, and therefore, by extension, carcass value.

Poultry breeding programs have been focused on improvement of growth and carcass traits, however, this has resulted in correlated changes in internal organ weights and increased incidence of metabolic disorders.

Quantum of genetic variability and the extent to which heritable and nonheritable variations are related to the characters, determines the extent of genetic amelioration. The present investigation was carried out in kharif, 2019 to understand the clustering pattern and correlation for yield attributing traits in aromatic landraces of rice. Here 90 aromatic rice landraces along with six check varieties were evaluated for 10 quantitative characters. Cluster analysis divided these 96 rice genotypes into 4 clusters.

Disease resilience is the ability to maintain performance under pathogen exposure but is difficult to select for because breeding populations are raised under high health. Selection for resilience requires a trait that is heritable, easy to measure on healthy animals, and genetically correlated with resilience

The data records of Murrah buffaloes from history cum pedigree sheets maintained over a period of 24 years(1992-2015) at Buffalo research centre(BRC), LUVAS, Hisar and Animal farm ICAR-CIRB, Hisar, were analysed to estimate heritability(h2 ), genetic and phenotypic correlation among various production and reproduction traits. Production traits whose genetic parameters analysed were Total lactation milk yield (TLMY), 305 days milk yield (305MY)...

At the same time, the breeding lines from the advanced generations are also used as parental lines for developing commercially exploitable heterotic hybrids. But, most often the source of early generations i.e., F3, F4, F5 and F6 segregating populations offer wider opportunities for achieving high success, because of wider genetic base.

The research work comprising of genetic variability, heritability and genetic advance as well as correlation and path analysis study for 12 quantitative traits in three genotypes of cotton (Gossypium arboreum L.) was carried out during 2015 and 2016 at Research Farm of Cotton Section, Department of Genetics and Plant Breeding, CCS Haryana Agricultural University, Hisar, India. The genotypic differences were significant for all the traits except number of monopods/plant and number of seeds/boll.

Thirty mungbean genotypes were evaluated for the estimation of genetic variability, heritability, genetic advance, correlation coefficient, and path coefficient analysis for yield and its component traits. A considerable amount of genetic variability was observed among all the genotypes for all the characters under study. GCV & PCV were highest for seed yield per plant, followed by harvest index, biological yield and number of pods per plant.
