WitrynaHeritability is an important concept in quantitative genetics, particularly in selective breeding and behaviour genetics (for instance twin studies ), but is less widely used in population genetics . Heritability measures the fraction of phenotype variability that can be attributed to genetic variation. Witryna15 mar 2024 · A high broad-sense heritability was estimated for plant height, stigma position, pollen viability, and fruit weight. Low heritability estimates were found for the number of flowers, fruit set, and yield. Despite the interaction, traits recorded under control and heat conditions were positively correlated. ... L.C.
