WebNarrow sense heritability describes the ratio of additive genetic variance to phenotypic variance. Genetic evaluation calculations use estimates of additive genetic variances. … WebThe high broad-sense heritability estimates and moderate to high narrow-sense heritability estimates reaffirmed the presence of dominance and additive gene effects in the inheritance of the measured traits. This result is contrary to the result of who reported low-to-moderate narrow-sense heritability for GYLD, agronomic traits and FAW ...
WebTranscribed image text: 22. When narrow sense heritability is high for a trait, offspring tend to resemble their parents for that trait True b. False 23. If the environmental variance (V) … 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.
