In this paper we assess the presence of assortative mating, gene–environment interaction and the heritability of intelligence in childhood using a twin family design with twins, their siblings and parents from 112 families. We evaluate two competing hypotheses about the cause of assortative mating in intelligence: social homogamy and phenotypic assortment, and their implications for the heritab...

The present investigation were to assess the Genetic variability, heritability, genetic advance, correlation coefficient analysis and path for chickpea(Cicer arietinum.L) genotypes 13 quantitative traits during Rabi 2021-2022 at field experiment center, Department of Genetics Plant Breeding, Naini Agriculture Institute, Sam Higginbottom University Technology Sciences, Uttar Pradesh . To perform...

This study investigated heritability for bovine growth estimated with genomewide single nucleotide polymorphism (SNP) information obtained from a DNA microarray chip. Three hundred sixty seven Korean cattle were genotyped with the Illumina BovineSNP50 BeadChip, and 39,112 SNPs of 364 animals filtered by quality assurance were analyzed to estimate heritability of body weights at 6, 9, 12, 15, 18...

H2DB (http://tga.nig.ac.jp/h2db/), an annotation database of genetic heritability estimates for humans and other species, has been developed as a knowledge database to connect trait-associated genomic loci. Heritability estimates have been investigated for individual species, particularly in human twin studies and plant/animal breeding studies. However, there appears to be no comprehensive heri...

For nearly a century, twin and adoption studies have yielded substantial estimates of heritability for cognitive abilities, although it has proved difficult for genomewide-association studies to identify the genetic variants that account for this heritability (i.e., the missing-heritability problem). However, a new approach, genomewide complex-trait analysis (GCTA), forgoes the identification o...

Callous-unemotional behavior (CU) is currently under consideration as a subtyping index for conduct disorder diagnosis. Twin studies routinely estimate the heritability of CU as greater than 50%. It is now possible to estimate genetic influence using DNA alone from samples of unrelated individuals, not relying on the assumptions of the twin method. Here we use this new DNA method (implemented i...

Abstract Flower bud thrips is one of the most destructive insect pests cowpea in sub-Saharan Africa. Information on genetic variability among germplasm and interrelationships traits under infestation would facilitate development resistant varieties. The objectives study were to assess for resistance, estimate heritability yield other investigate inter-trait relationships infestation. One hundre...
