Final answer:
Heritability scores of 0, 0.5, and 1 indicate 'No heritability,' 'Moderate heritability,' and 'High heritability,' respectively. These scores describe the proportion of variation in a trait within a population that is due to genetic factors. The correct option is A.
Step-by-step explanation:
The heritability score (h²) indicates the extent to which genetic factors contribute to the variation in a trait within a population. A heritability score of 0 implies there is No heritability; that is, the observed variation in the trait is entirely due to environmental factors and not genetic variation.
In contrast, a heritability score of 0.5 suggests Moderate heritability, indicating that about half of the variation in the trait can be attributed to genetic differences. A heritability score of 1 implies High heritability, meaning all of the variation in the trait within the population is due to genetic differences.
In the context of the question, the correct sequence for describing the extent of heritability for scores of 0, 0.5, and 1 is: A) No heritability; Moderate heritability; High heritability.
