Methylmercury (MeHg) is a persistent environmental toxin present in seafood that can compromise the developing nervous system in humans. The effects of MeHg toxicity varies among individuals, despite similar levels of exposure, indicating that genetic differences contribute to MeHg susceptibility. To examine how genetic variation impacts MeHg tolerance, we assessed developmental tolerance to Me...

Selection is expected to maintain primary sex ratios at an evolutionary equilibrium. In organisms with temperature-dependent sex determination (TSD), targets of sex-ratio selection include the thermal sensitivity of the sex-determining pathway (hereafter, sex determination threshold) and nest-site choice. However, offspring sex may be canalized for nests located in thermally extreme environment...

The objective of the current study was to quantify genetic variability, heritability, and advance as a percentage mean among 20 genotypes pea (Pisum sativum L.) using ten quantitative characters at Horticulture Research Centre (HRC) Sardar Vallabhbhai Patel University Agriculture Technology, Meerut, U.P, in years 2021–2022. results ANOVA revealed substantial variations across for each attribute...

A field experiment was conducted aiming to study the Assessing genetic variability, correlation, direct and indirect effects of yield contributing characters on seed in 20 Finger millet lines kharif season 2021 Randomized Block Design (RBD) at Field Experimentation Station, Department Genetics Plant Breeding. Phenotypic genotypic coefficient variation found highest ear head length (25.37& 2...

This research was planned to study the heritability (broad sense), correlation, genetic advance and behavior of different characters in segregating population upland cotton. The material consists fourteen crosses along with their seven parents. Parental varieties show significant difference for all traits under study. Plant height, ginning out turn (GOT), bolls per plant yield showed ranging fr...

Directional selection produces a change in the population mean of a phenotype, but this shift will only be translated into a phenotypic difference between generations if the trait is heritable, in the sense that there is additive genetic variance in the trait. Thus any study of evolutionary change must concern itself both with the factors causing phenotypic change and the genetic architecture o...

The popular Genome-wide Complex Trait Analysis (GCTA) software uses the random-effects models for estimating the narrow-sense heritability based on GWAS data of unrelated individuals without knowing and identifying the causal loci. Many methods have since extended this approach to various situations. However, since the proportion of causal loci among the variants is typically very small and GCT...

tall fescue is a cool season grass widely distributed and adapted to different environmental conditions of iran. superior seed-yielding potential of the plant is an important criterion during the seed reproduction phases of breeding new cultivars and as well under commercial seed production conditions. in order to evaluate germplasm and investigate the pattern of genetic variation of seed trait...
