The high narrow-sense heritability in E 2 (59.75%) and E 4 (57.76%) confirmed that sedimentation value was predominantly governed by additive genes. 3.1.3.

WebQuestion: Question 8 (1 point) Saved Listen A population with high narrow-sense heritability at the start of a selective breeding program is likely to respond well to selective breeding over many generations. WebExplanation: -Most eukaryotes have about the same number of genes. -some plants have 25 or 30 thousand genes and human had around 20 thousand genes. -restate the question: (how can the genome be larger without many more genes?) -transposons can make up a large portion of genomes. simplicity 1882
Heritability in broad sense and narrow sense Quantitative Inheritance
WebAbstract. Adult height is a classic polygenic trait of high narrow-sense heritability (h (2) = 0.8). In the late nineteenth to early twentieth century, variation in adult height was used as … High heritability of a trait, consequently, does not necessarily mean that the trait is not very susceptible to environmental influences. Heritability can also change as a result of changes in the environment, migration, inbreeding , or the way in which heritability itself is measured in the population under study. [9] See more Heritability is a statistic used in the fields of breeding and genetics that estimates the degree of variation in a phenotypic trait in a population that is due to genetic variation between individuals in that population. The concept of … See more Since only P can be observed or measured directly, heritability must be estimated from the similarities observed in subjects varying in their level of genetic or environmental similarity. The statistical analyses required to estimate the genetic and See more Heritability estimates' prominent critics, such as Steven Rose, Jay Joseph, and Richard Bentall, focus largely on heritability … See more • Behavioral genetics • Heredity • Heritability of IQ See more Heritability measures the fraction of phenotype variability that can be attributed to genetic variation. This is not the same as saying that this … See more Any particular phenotype can be modeled as the sum of genetic and environmental effects: Phenotype (P) = Genotype (G) + Environment (E). Likewise the phenotypic variance in the trait – Var (P) – is … See more In selective breeding of plants and animals, the expected response to selection of a trait with known narrow-sense heritability $${\displaystyle (h^{2})}$$ can be estimated using the breeder's equation: $${\displaystyle R=h^{2}S}$$ In this equation, the … See more Web2.4 Broad-sense heritability Breeding theory Broad-sense heritability estimates and selection response To define H for the 2-way and 3-way MET models, and to model the effect of replication within and across sites and years.
